Math Help

Aug 21, 2006

I have an artwork book which I am cataloging. Each page of the book contains 24 pices of artwork.
What I need to do is display a page number to whatever record number I enter into the field.

Example 2: I enter any record number from 1140 and the field will display 48 for the page the artwork is on in the book.

Example 2: I enter any record number from 1153 and the field will display 49 for the page the artwork is on in the book.

Example 3: I enter any record number from 457 to 480 and the field will display 20 for the page the artwork is on in the book.

Thanks for any help I can get on this

Best Way To Do The Math

Nov 10, 2004

I am a wiz at formulas in excel but am not sure yet how to make them work in access. I have a main form into which I put the date recieved of many items for each facility. Next to each of the dates I have entered I want to have a non inputable text block that will look at the date then do the necassary math automatically. Some of the formulas will also contain conditional statements based off of a date, type and rating. Can anyone suggest the best way to do this or point me toward a resource that explains how to use formulas in access. Here are a few examples of the formulas that are already in place in the excel version.

=IF(I28="Unsatisfactory",C28+60,(IF(F2="AA&E",C28+365,(IF(F2="Major Funds",C28+365,C28+1470)))))
in the above formula C28 is a date entered by the user, otherwise most formulas I need to input are simply (date + 1 year or date + 4 years)

Any advice would be greatly appreciated.

The other is that i want to be able to check the previous cell(year) and see if the number has gone up or down?

selects already made when I open the form

Math Operations On Values Question

May 13, 2005

I have created a table that holds the inventory information of some items i have in stock. What I want to do is this:

1.)When a customer orders something, i enter the quantity ordered and hit a process button. When this button is clicked it automatically reduces my inventory count to reflect the reduction

2.)When I receive shipments, i want to enter the information and hit process so that it automatically sets my inventory counts to reflect the addition of the new units

I am having trouble figuring out how to go about doing this. I was thinking of somehow setting up some textfields and then adding buttons that set fields accordingly.

Any help would be most appreciated.

Forms :: How To Do Math With Two Different Units Of Measure

Oct 30, 2013

I have a table with some prices that are charged by the pound and some that are charged by each.

tblPrices
ID 1 - 1.00 per pound
ID 2 - 1.50 per pound
ID 3 - 2.00 per pound
ID 4 - 5.00 each
ID 5 - 7.00 each

My form is set up so that way I count how many containers I have and their weight, separately. I need ID 1 through 3 to do the math based on the pounds (essentially $1 per pound at 36 pounds) and ID 4 and 5 to do math based on how many of each are there ($5 each, and there are 3 of them).

Dealing With Null Values In Math Expressions

May 11, 2006

Hi all,

I am in desperate need of some advice. Today I set to work building some math functions in my queries to calculate delays/turnaround times for work, etc.

I have found that where there are null values in my table - the calculation seems to break down.

Let me explain...

In it's simplest form (I have removed some fields and will deal with DATE only, not TIME which is a seperate field) I have the following -

Date_Received
Date_Started
Date_Pended
Date_Recommenced
Date_Completed

I have the following expressions in my query -

Turnaround: Date_Completed - Date_Received
TimePended: Date_Recommenced - Date_Pended
TimeInactive: Date_Started - Date_Received
Workrate: Turnaround - (TimePended + TimeInactive)

The query calculation will only work when all fields contain a value.

For instance, sometimes the work may be started, then completed. Skipping the 'Pended' and 'Recommenced' steps.

Can anyone tell me what I need to include in my maths for Access to treat a null value in the table as zero? Or any other approach.

Please help!!!!!

Thanks

Rob :eek:

Help A Newbie Understand Simple Math Functions

Aug 6, 2006

I am completely new to Access but probably all I will need is a gentle push in the right direction. I'd like to think I'm fairly quick at learning new things. Thank you in advance, here's where I am, (first step anyway):

Table 01 Parts List
ID - name - cost

Table 02 Item List
ID - nick name - description

Table 03 Items to parts relationship (this is where I fall apart)
ID - Item ID (relationship to table 02) - Item nickname - PartID (relationship to Table 01) - Part name - Part quantity.

What I am trying to do:
I resell items in table 02 which are built of various parts from table 01. I need to generate a table that says:
Item 1 is built from 4 of part 1, 2 of part 2, 9 of part 3, and the total cost of parts for Item 1 is x. I want to update the parts list cost on a regular basis and have the item price change reflected.

If I can understand how to make this work, I can ultimately add in labor and overhead etc etc. Baby steps for now.

Thanks again
-Richard

Here's a copy of my sad little db

Forms :: Performing Basic Math On A Specific Column / Row

Oct 10, 2014

how to do anything with it outside of tables and queries. I have been tasked with creating a form to do fairly basic things. Via tutorials I have managed to use the Expression Builder to do virtually everything I need except one thing.

I need to pull a value from row 2 in a specific column from a subform and subtract it from row 1 in the same column and subform leaving behind a + or - number for the user. Similarly, I need to do the same but subtracting the LAST ROW from row 1. If there is only one row at the time the operation is being performed, a value of No Data needs to be returned instead of a number.
