Hi MeganMetro,
I understand you're trying to run this report through the browser. At the moment, job budgets entered in the desktop app don't flow through to the browser version, so if you're running reports there, that budget data won't be available.
For now, the workaround is to use the same version where the budget was entered. So if the job budget was set up in desktop, you'd need to view or run that budget reporting from desktop as well.
I know that's not ideal when you're using the browser for reporting, but at this stage it isn't supported across both views.
If you'd like to see this available in the browser as well, I recommend posting it on the Ideas Exchange board so the development team can gauge interest in the feature.
Regards,
