Are you joking? ;) You have to do only one change a time!
you have to
a) remove the attribute required of the field. Insert and then post. Does the error show again? If so, it could be a IB_Date problem, if not it is not.
b) set the attribute required of the field again. Remove the IB_Date component. Since you told that you leave it empty, this will be not a problem. Done that, recompile, insert the record and post. Does the error show again? If yes, it's not a IB_Date problem
OK?
Anyway, could you please tell us what is the error message?
Thanks
