I have done all the steps and when I go to fill in the information the error message does not show up.
The blank still accepts a value more than 100.
But this is how when I fill in information it doesn't show that there is an error.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
