If it's the same problem as the other thread (Sql Server) where the day and month needed to be reversed I'd try: strSql = Insert InTo MoneyEntries (Amount EntryDate Description IDCategory) Values (' + am.ToString() + '' + dt.ToString(MM/dd/yyyy) + '' + desc.ToString() + '' + rdr[0].ToString() +')';

Vulpes · Answer

There looks to be a superflous single quote after the final closing bracket which needs removing: strSql = Insert InTo MoneyEntries (Amount EntryDate Description IDCategory) Values (' + am.ToString() + '' + dt.ToString(MM/dd/yyyy) + '' + desc.ToString() + '' + rdr[0].ToString() + ') ;

It may be that the DateTime you're passing (on which by default the ToString() method is being called) is not in the correct format for whatever database you're using. We had another thread on this problem recently ( http://www.c-sharpcorner.com/Forums/Thread/131973/inserting-date-value.aspx ). Also I'm surprised it works at all without a space before 'Values'. I'd also remove the single quotes for the int value.
