Pop up message when data is entered

[jlbrowneyes]

Hello. I am new to the site but have already found a TON of helpful information! I would like some assistance with a 2007 Excel spreadsheet. My company currently shares ONE spreadsheet to generate new project numbers (Shown below). My issue is once a new number is assigned, it is supposed to be entered into our accounting software but that doesn’t appear to be happening in some cases.
Is there a way that a pop up message can appear when column G is populated (Entered by)? Something like, “please be sure to enter this XYZ”.

Thank you in advance for any advice or assistance you are able to offer!

That's what I thought but I tested it and it didn't work on their computer???????

Did you save it before they opened it? Are macros enables on their end?

I did save it because I closed it out and reopened it from my computer and it worked. I will go check his macro setting. That is, I assume, the drawback should they not have macros enabled.
