For one, you use a double quote instead of an apostrophe for quotes. Second, you try to multiply a string by a field. Can't tell you what else is wrong without some error messages. Also, it would be useful if you actually explained your problem rather than just stating that you have a problem and posting some code we know nothing about. You should also state which type of SQL you are using... not sure why you tagged this question with C#.
