Either he made a mistake typing in the URL or a glitch inserted the space between theo' and the 'm'. Either way, just delete the space and enter the URL.
Also, I'm guessing you were not logged in when you clicked the 'reply' button, correct? There's currently a forum glitch regarding that, which is likely why your reply to this old thread began a new thread.

<(NT) try this http://www.envisiondisplay.co m/main.asp>
nothing happens. can u advise?
