Using: if TextboxA > TextboxB make image visable

This works more frequently, however the winner image does appear incorrect at times and other time does not appear at all;

Apologies for the inconsistent etiquette.

Red = Identify Winner Code

Blue = Reset Values Code

Both Sets of code are on a different layer.
