Move between 2 forms

[jbphoenix]

I have a form with customer info and a subform with details. I need certain fields to be filled in by the user before they can proceed to the subform. How do I set something up that will notify the user if a field is left blank on the main form?

in the on enter of the subform u can put
if (isNull [main form fieldName] or [main form fieldName] = "") Then
MsgBox "u must fill out all fields in main form"
[main form fieldName].setfocus
Else
End if
