Hi Kelly, I'm not sure what's going on. In Classic, are you in the weight goal tab or the weight tab? In the weight goal tab, there is a box for goal weight; what happens when you try to put something in there? Can you post a screen shot of what you're getting when you try to enter a weight goal? They are trying to replicate the problem on their end and that might help.
