I have a form, which has a control with a Default Value. I need to hide this value or make it null, if the value of another control is also null. Both are text fields.
ie, Checklist has a default value of "Xray". If [Cast No] is blank, I don't want "Xray" to appear. I've tried all sorts of code, but nothing has worked, and I wondered if it was because I had set the default value in the table.
