Error msg...

Hi all, I'm using Oracle Forms Builder and I try to connect to Oracle server but I can't and there is msg pop up. "ORA-12154: TNS: could not resolve service name"

I have no idea about this, because this is the first time im using this. Does anyone know about this problem?

Just a wild guess, but you sure you put in the right Database?
Like a said this is just a guess
