I have a spreadsheet that I'm using goal seek on, but I have two different scenarios that I want to provide the user.

Choose to find for X...do this goal seek, choose to find for Y....do this OTHER goal seek.

I was thinking that what I need is to create a combo box that asks the user which goal seek method they would like. Presumably this would be by using a radio button, and that button's value would be equal to a goal seek function that I determine. But within that function I would also need to have a couple of input boxes. I'm comfortable with creating the input boxes, maybe not in the middle of a formula, but creating a combo box with radio buttons I have zero experience with.

Is anyone able to help point me in the right direction?
