Hi,



I have a checkbox on my custom outlook form which needs to be checked by the user before it is sent. For some reason the "A value is required for this field" is greyed out. Could somebody please help me with a formula or solution that would force the user to check the box and not leave it blank. My checkbox is associated with a Yes/No field type, format: Yes/No and property to use: Value. I've tried all different options, i.e. On/Off, True/False, TripleState, etc. but to no avail.

Any assistance would be greatly appreciated.
