Gerard,

The THISFORM syntax can only be used within a form and automatically refers to the form the object is contained in.

When you get to your oApp you're not on a form any more. If you want oApp to know which form to validate you will want to pass in the values of the control(s) you are validating.

Use something in the Save button like

LOCAL lcParm1, lcParm2, lcParm3

lcParm1 = THISFORM.txtName.Value
lcParm2 = THISFORM.txtAddress.Value
lcParm3 = THISFORM.txtCity.Value

oApp.ValidateForm(lcParm1, lcParm2, lcParm3)
