I am trying to do a calculation between numbers that were entered in the same
table on different dates. My structure is this I have one Table with all my
client information. Then I have another table that has sales entered into it
on a weekly basis. I created a form with the client info and added a subform
for all the weekly sales to be viewed while in this form. I want to take an
EndingSales column and have it subtract the previous weaks ending sales. and
have that number displayed in a text box. Does that help at all?
