Hi,
If you select the root / parent in the hierarchy (form1) and put the following javascript in the docReady event:
app.runtimeHighlight = true;
This will turn on the light blue shading to all fields and give a red border to required fields. It is a good idea to put the following in the docClose event so that when the user opens a different form, the Highlight is off.
app.runtimeHighlight = false;
Hope that helps,
Niall
