Button to change cell contents/formulas

I apoligize if this is in the wrong spot, not sure where to start (or even what to search for here), so I'll just explain what I want to do:

I have a single Excel Workbook that has 3 sheets.

Sheet 1: Output
Sheet 2: Current MTD
Sheet 3: Budgets

On the "Output" sheet I pull data currently from the "Current MTD" sheet through various formulas to output the data and metrics I need. What I'd like to be able to do is have a button that I can push that would change all of the formulas so that the main sheet now pulls from the "Budgets" sheet and applys different formulas.

Basically I'd like to change some of the data and formulas at the "Output" sheet at the click of a button, and then change them back either with the same or different button, whichever is easier. I have no experience with VBA scripting or macro's (if that is what this requires), but am a geek and so have a passing understanding of programming and am willing to learn.

As always, thanks a ton in advance for any help or direction!!

We would need to see both sets of formulae to help you with this.

Thank you so much for the quick reply! I've attached something similar to what I'm needing. I'm not looking for a perfect solution here all wrapped up, but more of an example so that I can extrapolate from there. As I said, I'm no guru but I can follow directions and expand on something once I know where to start.
