>The display is correct with "37 ", with the cursor after the "7", so the user will not have to enter all 4 numbers(as text). When the last 2 numbers are added, the display is (ex.."3715"). All that is added to the table is the "15"...sometimes, and other times, its the "3715".

Its probably there part of the times because you actually key in 37? DUnno, what I do know is, that InputMask isn't made for that sort of thing. Try using a default value in your field (or 37) or when you add the record in your form. Or, if its alawys gonna be 37, why even show or store that in teh field, don't you know what it'll be?
