I need to create cancel button to ProjTableEditSubProjPrompt form.

I need to create cancel button to ProjTableEditSubProjPrompt form. So that when user presses cancel all the projtable information that has been changed cancels and updates to original state that was before updating.

I assume I have to use something like "projtable.data(projtable.orig()); but how to get projtable record? Can this be done in clicked()?

Thank!
