Ensure A Calculated Field Is Always Positive
Jan 10, 2005
I have a calculated field which sums the quantity field for all transactions by the part#, lot# and location. (A part number could be in several different locations and lots and are treated sperately - if they are in the same location with the same lot number they are summed).
To add quantity the user enters the data using a form. To issue (subtract) the user uses a minus number (eg -20). The calculated field sums all these and outputs the current total.
How can I make sure this is always positive.
Ie. When the user does an issue the qty they specify will be less than or equal to the current total according to the sum calculation.
Thank you for any help

Is there a way to format a memo field to ensure that sentences begin with capital letters. There might have been something in the strConv function, but it seems my hopes are dashed?

My query contains two calculated fields [TaxSavings1] and [TaxSavings2], which are based on some currency and number-type fields in one of my underlying tables.
I just created another field in my query which looks like: [TaxSavings1]+[TaxSavings2]. Instead of adding the two fields, it actually lumps the two numbers together. For example, if [TaxSavings1] =135 and [TaxSavings2]=30.25, it will give me: 13530.25. I need it just to simply add, i.e. answer of 165.25.
Does anyone know how to correct this? Thanks in advance.
:confused:

Can someone please help me?
I have a combo box on a form that the user can select a player name.
Under the combo box I have a label called "Show me information about selected Player: that once clicked takes the user to another form which has all information about the player that was previously selected in the combo box.
Everything works fine UNLESS the user forgets to select a playername from the combo box and clicks on the label anyway. Obviously no player name was selected so a blank form opens which is a problem!
How can I ensure that a player name is selected and prevent the user from clicking on the label below without having previously selecting from the combo box?
If anyone can please help I would appreciate it so much.

What is considered the right approach to ensure a record entered in a form is unique. For example if i have a field:
Brands. Flavour
Walker. Ready salted
Smiths. Cheese and onion
Doritos. Ready salted
Walker. Ready salted
So what is the best way to ensure the third entry is fine as whilst ready salted already exists it doesnt exist for doritos but the fourth entry would pull up a msgbox refusing the entry as it is a repeat of entry one.

I am developing an Access database, and using the Access 2007 Developer Extensions to "compile" it into an installable program which includes the freely distributable Access 2007 RunTime, for users who don't have it already installed.
I am planning on charging a subscription fee to use my Access database. Are there any existing method for handling making sure the user's subscription is still active, and if not, either locking them our or preferably making everything read-only? If there aren't any existing methods anyone can point me to, does anyone have any ideas?
I plan on being the person who installs the application the first time, however I'm sure instances will come up where I instead mail the user a CD for them to install.
Regardless of whether I complete the first install, I'm not interested in going to each users' location periodically regarding the subscription.
I'm more interested in going the route of the user typing in some type of registration code, which is validated for read/write access for a period of time.
I don't want to rely on the user having an internet connection, but if they had one, I could certainly go the Microsoft model (try internet verification, if it goes wrong or there isn't a connection, have user call in.)

I am designing a Web Database with a bound form to a submit table.
On the form, I have a combo box with selections that should influence the value to be displayed in a textbox also on same form.
For instance the combo box for Staff Name contains list of all Staff and I want the textbox to automatically display the level of the staff that was just selected in the combobox.
I know how to get this done using a combobox but my boss insists that the level should be automatically displayed in the textbox once combobox selection is done.
Using the combobox for level, I used the select statement in the RowSource property :
SELECT Staff_List.Level, Staff_List.Staff_Name FROM Staff_List WHERE (((Staff_List.Staff_Name)=[forms]![frmtest]![cboStaffName]));
I am in a dilemma of how to replicate this for the textbox because textbox only has control source and no RowSource where I can put this select statement.
Also, I will still need to bind this textbox to the submit table with the column name "TxtLevel" in the control source
Please see attached sample access db.
Also note that I cannot use action queries or VBA because it is a Web database and not a client database.

Table1 contain Two fields (3Months) and (6Months)
Table2 contain Two fields (3Months) and (6Months)
the table 2 is the source of a form that will let the user change the numbers. table 1 should change Date1 and Date2 Fields based on the two fields (3months) and (6months) if i want to make a lookup wizard it should be changed manually and if i make a calculated field i can't find other tables in the expression builder

I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:
10Jul15: Sales
and then adding Criteria like:
EndDate = #10/07/2015#
It doesnt work.

I don't know if it's possible, but is there any way of forcing the random autonumber generator in tables to be a positive number only?
The autonumber as I've searched on the forum can be a positive or negative number and I'd like to use the random autonumber feature as a primary key for account numbers for my database, but not using the negative numbers as they will look like odd account numbers with the leading negative.
I could possibly remove the leading negative, but there's then the chance that you'll have duplicates.
Thank you!

Hi.. I am a beginner using access and there is probably an easy solution for this which i dont know about!
I have made a query where i calculate the tax deductions for a payroll system. my problem is that different workers are to be taxed differently given maritial status and number of kids as well as net income.
I have managed to calculate everything with the kids and wifes but now i need to sort the table after how much they earn to deduct taxes. I have a "first stage NetPay field" now, where i can see the Gross pay minus allowances for wifes and kids.
Now, if that value(first stage netpay) is under 8840 no more deductions are to occur. If the value is between 8840 and 10000 i have to deduct 15% of the excess above 8840
If the value is between 10000 and 20000 i have to deduct a further 174+ 25% of excess over 10000
If the value is above 20000 i have to deduct 2674+ 31% of excess over 20000
So far what i have done is make a new coloumn, where i take "first stage netpay field" and subtract 8840. If the value is negative i thought i could show only the positive values by enterin >0 in the criteria field for the query, this however will make no posts show up..
(I tried entering Abs() in the Field coloumn where i made the expression, and this worked. )
So my question is: is there a function like Abs() i could use that would convert negative values into 0?
Or do any of you guys have a better idea of how to solve this?
Hope someone can help me...

I have a field on my report that contains positive and negative numbers. I'm trying to find a way to Sum the column twice for two different fields (one for positive sum and the other negative) To make this easy let me give a small example with explanation of the issue I am having. 14 rows of data containing positive and negative numbers in a field called [Rooms]:
1) -1
2) 1
3) 1
4) 1
5) 1
6) 1
7) 1
8) 1
9) 1
10) 5
11) 1
12) -5
13) 1
14) 1
The positive numbers represent confirmations, the negative numbers represent cancellations. I need 2 fields to separate these. The first field's control source is Sum([Rooms]). No problem there. Access does the math and comes up with "8" confirmations which is correct. Then in the second (Cancellation field) I try something like Sum([Rooms]<0) to get the negative numbers which should add up to -7 (-1+-1+-5), but instead I get -3 because it's not summing the values, it's really returning the number of rows that has a negative number. Is there any way this can be done at the ControlSource Property of a report field? Or if I could do a "Where" clause in a ControlSource I could acheive it another way, but I don't that is possible. Is this just something I'm missing with the way I'm stucturing the ControlSource or is it not possible. Or alternatively, is there a way to separate it in the query and have a separate query field for positive and negative going into the report. I can do one or the other in the query but I can't seem to do both without showing values of each type in both query fields.
Thanks for your help!

I am trying to to find a way to show all the positive values with nagative, in order words, if the value is 10,000 is should be followed by corresponding -10,000 so that the user could investigate if the entry is a reversible GL.

I have an expression that converts a string to positive/negative number. It seems to be working fine, however, it doesn't convert "00000000001}" to -10. It shows as 10.
This is the formula that I am using in my query:
PJUNAccrual: IIf(Right([PJ_ACCRUAL_ADJ_X],1) Between "J" And "S",-1,1)*(Val([PJ_ACCRUAL_ADJ_X])/IIf(IsNumeric([PJ_ACCRUAL_ADJ_X]),100,10)+(IIf(Right([PJ_ACCRUAL_ADJ_X],1) Between "A" And "I",(Asc(Right([PJ_ACCRUAL_ADJ_X],1))-64)/100,0))+(IIf(Right([PJ_ACCRUAL_ADJ_X],1) Between "J" And "S",(Asc(Right([PJ_ACCRUAL_ADJ_X],1))-73)/100,0)))*100
