First of all, you ought to retain these values or else they might be
deallocated later, which would cause a crash if your application tried
to access them...
if(openNewWindowWithPageType == @"Empty Page")
{
}
Second, this type of comparison doesn't work, because it's comparing
the memory addresses but not the content. Just like you'd need to use
strncmp() to compare two C strings, you must use an NSString method to
check the equality of two strings:
if ([openNewWindowWithPageType isEqualToString:@"Empty Page"])
{
}
..and so on. See the NSString documentation for details.

Doh! Didn't even think about that. I've been working with Booleans all
day and I'm just in that mode. Thanks!
