For Step 110, after entering the First and Last Name, Company, etc., the step says to check the box that says "Assign using active assignment rule checkbox". However, I do not see the option for that on my screen.
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!
