I have budget worksheet that I use and it works very well. I am trying to have a check register on another tab for that month with drop down categories that will automatically change the values in my budget. For instance if I budget $300 for groceries and I go to the store I want to put into my register that I spent x amount of dollars on my register tab and if I choose groceries in the drop down menu then it would automatically add that to the budget tab. I am sure this is possible, but I just simply don't have that skill. Thanks so much in advance.
