upperTheWebPage = upper(TheWebPage)

It's 

while equal(TheWebPage,"") do

and the bottom of the loop sets TheWebPage back to "" if it hasn't 
exited already. So does the start of the loop, and the line before 
the loop. Full code for the loop is at 
http://designerthinking.com/temp/whiledemo.e

The same loop is in use in other apps, which would crash horribly if 
it made the same error as this app is doing, same as this app is 
crashing.
