Hi
i need a help.
i have an input layout with the following structure:
CHAR1| datefrom| dateto |amount
I need to control that the user cannot enter, for the same value of char1, a range smaller than the previous entered one.
CHAR1| datefrom| dateto |amount
A |01.01.06|31.12.06| 100
A |01.03.06|31.12.06| 100 <<<----how to avoid this input???
can i use xls macros?whic one?
Thanks
Stefania
