What nhawk said before is true - you cannot use the <form> tags. What problem are you having now? I didn't understand the error message you posted above, maybe because I don't understand exactly what the javascript is trying to do.

I did as nhawk said, but not work, and in VB3 it still works fine :(.
This is file .js

This line in your plugin:
You have no variable $mylist, so why are you registering it for use? Don't you mean $mylistcardposted ? If so, you also need to change that variable name in the template too.

Oh, I missed the part where it works in vb3. Maybe that will work then, I'm not sure.

I changed it to sync, but it is only current issues show up temp (or can add temp by hand).The problem I'm interested in is this plug in it can not submit thread.

Please review video once more options has been shown on newthread but cannot be submit

You can add my plugin to attach and test.

I cannot test something that is incorrect. You CANNOT have <form> tags in your template. You CANNOT put a form within a form or it WILL NOT WORK. Take a look at your page source - you have a form within a form. That WILL NOT WORK.

I tried again and it worked, thank for all :)
