Yes, the value is numeric by default and I already was using SelectOnEntry = .T..

I have tried Format KR, but nothing different occurs.

>Is the value by default numeric? Set the select on entry to Y or delete the 0 when keying the value. Also set the format to R and the input mask to 9,999,999 or whatever.

>>When typing a new value, such as 1, into a blank text box that has an input mask like 9,999,999, an extra zero is added and the value becomes 10 instead 1. The extra zero only appears if I press TAB. When I press ENTER no extra zero appears.
