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.
