>The problem lies in the fact that if the date is valid, the value of the textbox will be a date type. So it's like doing isblank(ctod(allt({06/05/2001}))), which gives an error.
why would .value = {06/05/2001} ? I'm not familiar with a condition that would do that, althought I don't use this when the textbix is bound - that may be why in your case. if so might what to add
if vartype( form.textbox.value ) <> "D"
isblank(...
