Your problem is that the method 'AddValue' does not take zero arguments. This is stated quite clearly in the error message you are receiving. Take a look at the AddValue method in your code or the documentation for it (if you didn't make it) and see what arguments it takes. Then double-click the error to find the line that is causing the error and make sure your call to AddValue is supplying all of the correct arguments. Next time, as the other guy said, post in the right forum and clean up your grammar and you might get help faster. Steve
