Count your curly braces. Do you have one too many or too few?

Is it just me? I think ErikD99 should reply in this thread Help!!! and should not create a new thread regarding this one...

Also What?!?! does not describe his problem.

Hey Darryl. Yeah, his subject header is not exactly meaningful nor informative. Hopefully he'll do better with this next thread.

I will send him a private message asking him not to create new threads before responding to responses made in previous threads. This behavior will not encourage folks to continue to help him.

Looks like he took that to mean he should create a new user account.
