Deadline And I Need Some Assistance Please

I created a form using a text boxes by using the field list icon and dragging the field I wanted to make into the text box onto the form. In the properties of that text box, under the format tab I set the format for "short date". Under the data tab in the properties of the text box I put in the control source this forumla =DateSerial(Year([Date of Service]),Month([Date of Service])+10,Day([Date of Service])). "Date of Service" on my form is the name of the source field it calculates from. What the forumla does is calculates from the date entered into my Service Date field and whatever date is in that field it adds 10 months to it. This field with this formula in it caluclates the date of my contacting the customer to setup an annual service for them. I also have another field that calculates the annual service date using the same formula only changing the +10 to +12.

When the Date of Service it entered the Contact Date field automatically adds 10 months to the date entered into the Date of Service field. Same of the Date of Next Service field only instead of 10 months it adds 12. So my formulas are correct. However when I go to my table I can not see any of the caluculated dates entered into the table. I can see it in the datasheet view of my form. My question is how do I create a query to pull only contacts dates from this form for a specific time frame? When I attempt to create a query I can only see table fields which do not contain the formulas for calculating the dates. Or can the fields that calculate the dates on my form be linked so the calculated dates are linked into the table and updated on the table when I update the form?

Keep in mind I am new to access so please give very detailed and specific instructions on a solution for this issue.
