Hi Pharmastore.
Having the right cost for an item is imperative to keep your accounts accurate and up to date. I'd be happy to help you with getting the change cost pop up showing again.
First you should open a sample company in your QuickBooks Desktop and make the change there to see if you get the pop up again. The reason for this is to see if the issue is in the company file or the program itself. To open up a sample company close your current company file. When you see the no company open page click the sample file option at the bottom. If you don't see the pop up message when you change the cost of an item the issue would be with your program. At this point I recommend downloading the Tool Hub to fix this error and also try doing a reinstall.
If it works in the sample file then it could be due to your company file. You can follow the steps in this article to troubleshoot this issue.
Should you still run into issues I recommend contacting our support team so they can work together with you to get this resolved. You can reach them by calling the number in this article.
Have a great day!
