itunes will not let me spend anything on a app upgrade for some reason??I have $102.00 in my acct.?

Are you referring to having this money in an iTunes Store account? And what happens when you try to make a purchase?

You will need to do what it says, contact iTunes Support. These are user-to-user support forums, if you thought you were contacting Apple by posting here. Go here:

to contact the iTunes Store.
