Hi Dennis, I'm an independent adviser and will try to help.
But I need help from you to do so. The error message you are getting indicates there is a syntax error in your coding. But to spot the error, we need to see the code. So please respond with the code behind your button. It would also help if you could step through the code and find the line that throws the error. You can try doing a Debug of the code and see if it highlights the offending line.
Please help us help you.
