FormM@iler - Mail Subject from Post Subject.

the line 20 of FormM@iler.php;

$subject[0]="Subject of mail.";

Will make the subject in mail program: Subject of mail.
But i like to use the users chosen subject to display.

I use this in my form:
(i replaced every >< with »« so it will show)

«select name="Subject"»
«option value="Information"»Information/«option»
«option value="Pricing"»Pricing/«option»
«option value="Remaining"»Remaining/«option»
«/select»

How can i change this without too much change in the FormM@iler.php?
