Dear all,
In my table design,Because I need to accept No value , I can not use NO
duplicate index for my field , but I shouldn't let duplicate values in it. to
develop the need I check the value in the data entry form using "Find first"
of the record set. On my own computer it is OK and no duplicate value can be
entered. but users CAN add duplcate value.(mine is office xp but some use
office2003). what should I check? and if there are better solutions please
let me know. tnx in advance.
