How are you going know when to save the form? Are you going to have the user press a button? With a little more detail, I can give you what you need.

One method is to set a flag varaible and run thru the items looking for blanks.

Assume you have a control array of text boxes

DIM flag AS BOOLEAN
flag = True    'Assume all are filled
FOR ndx = 1 TO Text1.UBound
 IF len( Text1(ndx).Text ) < 1 THEN flag = False
NEXT ndx

When you get out of the loop FLAG will be False if any item is blank.

BergJC is right, this code should be in the CLICK event of your [Submit] button.
