Remove/Ignore spaces at the end of multiple text entry fields - Javascript question

Hi
Yes, I got there in the end...!

This script will run through the variables TextEntryX to TextEntryY (you can specify the first and last in the series by changing X and Y below to numbers) and replace the input in each of those variables with a "cleaned up" version with spaces and apostrophes etc removed. 

var p = GetPlayer();

for(var i = X; i < Y; i++) {
var textentry = p.GetVar("TextEntry" + i);
var newTextentry = textentry.replace(/^\s+|\s+$|\'/g, '');
p.SetVar("TextEntry" + i,newTextentry);
}
