Hey, I was gonna make a comment on the absurd page count (a script like yours should rarely exceed 110 pages), then I noticed that your margins were way off.
Lazy me would just tell you to download celtx -- a free screenwriting program at
http://www.celtx.com -- or go through all your margins box in options and click "Default".
Not so lazy me would give you the correct (I think) margins:
Left: 1.5 inches
Right: 1 inch
Top: 1 inch
Bottom: 1 inch
Screenplay Element Margins:
Slugline: left margin 1.5 inches
Action: left margin 1.5 inches
Character name: left margin 3.7 inches
Dialog: left margin 2.5 inches, right margin 2.5 inches (or 6 inches from left edge of page)
Parentheticals: left margin 3.1 inches, right margin 2.9 inches
(I don't even know what that means and I've been writing for a while now.)
If I were you, I'd just go with lazy me and download celtx. If you're just starting out with screenwriting, celtx is easily the best tool you can have. And it does all that margin junk for you.
