What do you mean by "I Can't do Function Create"? Does it throw an exception? it's not working at all? if it does throw an exception, what is it?

It looks like you have so much code it's wrapping over the button to add a comment so I'll add it here as a Solution instead.

1. Only post relevant code. It's hard to read through all of this code. For example, the Delete method is not relevant to your question. Click improve question and clean it up.
2. I don't see anywhere where it is calling your code to create the record.
3. Debug your code. Put breakpoints to make sure it's actually running what you think it is.
