I have a workshop report with 3 columns formatted as a general number with
zero First column is the maximum spaces available in each workshop.
Second column is the total spaces filled for each workshop
I want the third column to show the open spaces availbe in each workshop.
Can this be done easily?
 
If the 2 fields are numeric, you can create a text box with a control source
like:
=[Max Spaces]-[Spaces Filled]
