I have completed Lab2b but my screenshot # 3 is different from screenshot provided in the instructions. Please see attached the screenshot of my own work . The maximum value for average investment amount on in the screenshot provided in the instructions is 800,000 but the maximum value that I have on my graph is 700,000. Besides that the rest of the values doesn't agree as well.
Sorry you're stuck but there's almost always a pretty easy fix! Don't try to start all over again–not necessary! Don't start undoing stuff and don't uninstall Max's Pitch Package, etc.
There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. Check that first but if you can't find it there, post your problem + a screencap in the proper category below & we'll post a solution back ASAP!
