Sorry but I have got lots of solutions

Don't use the same name in rowsource and controlsource and I got lots of
kinds combox.valid() The one is worst then the other. But the combo is not working at all. The only problem I have with my on combo is I can't change
a value in the table. The rest is working fine. It should be wrong but what most a beginner do to solf this problem??
