Camera Height Interger Trigger?

Heres the basic rundown of the problem I'm having, I'm trying to make a trigger so that when type something like "-view150" it will set the Camera Height to 150, but its not that simple, I want it to (and i know it can be done cause ive seen it b4) be able to set the camera view to anything from like 100-700. . . any thoughts? Please just say so if you need me to clarify anything.

Event: Player - Player 1(red) types a chat message containing -view as a Substring
repeat that so event has every player in it

Condition: (Real((Substring((Entered chat string), 7, 9)))) Greater than or equal to 150.00
(Real((Substring((Entered chat string), 7, 9)))) Less than or equal to 700.00

Action: Camera - Set (Triggering Player)'s camera Height Offset(is this what you want?) to (Real((Substring((Entered chat string), 7, 9)))) over 0.00 seconds

I can get everything else to work except for this part I think, my Condition always ends up looking like this: (Real((Integer((Substring((Entered chat string), 7, 9)))))) Greater than or equal to 1.00

That red part is where I think there may be a potential problem. . . any thoughts?

Thanks, I got the trigger working. You've been a big help, thanks to you I've actually set up a couple other triggers using this format =D

No problem.
