Can i debug the form's event??? i facing a problem when i doing Save Data.

My problem is this way

Once i click Add, i disable the Vcr Bottons, and it suppose to be Enabled only when i click on Cancel Button, But then, when i save the data, i have some validation like

if empty(.txtno.Value)
Messageb("Empty",0,"Message")
.txtno.SetFocus()
Endif

I am expecting the txtno received focus and the Vcr button still remain disable...but anyhow...this Vcr button always Enabled once the program test out all my validation.....what wrong??? hhm...

please help me how to debug.

Thank in Advance
