Form check box button help

Hi there,

I am new to Oracle Forms, I need bit of help in Check Box.

I need to edit an existing form, and create a check box for users. when ever they select the check box. It enters 'D' char value in ABC table else it inserts NULL.

I hope you understand what I mean.

Thanks

In the check box propery pallette, list of values, set what is displayed/what the value is.
