Making a Cell Manual Entry or Return Calculated Value Based Upon Ratio Button Selection

[Brandon81]

I currently have a cell that the user inputs an numeric value into (highlighted in yellow). What I am trying to achieve is if the radio button selected is "YES" then user still can manually enter a value into the cell but if the radio button is "NO" then the same highlighted cell now returns a calculated value and can't be manually keyed/overwritten while selection is "NO". I am wondering if that is possible with conditional formatting or some other way. Is this possible and if so, how do I set this up?

You'll need to use VBA for this. To start, the code that I'm putting here is for ActiveX radio buttons, not form radio buttons. One button is named 'yes' and the other 'no'. The grouping property should be set so that when one button is clicked, the other is turned off automatically. And lastly, this involves protecting the sheet...so any cells that you need to remain editable, must have be unlocked.
So, in the developer screen, go to the sheet where your buttons exist and paste this code. You can set the password to one of your choosing, and also set the formula to whatever you need it to be.

Private Sub Yes_Click()
ActiveSheet.Unprotect Password:="password here"
Range("B2").Locked = False
ActiveSheet.Protect Password:="password here"
End Sub

Private Sub No_Click()
ActiveSheet.Unprotect Password:="password here"
Range("B2").Value = "=C2+D2"
Range("B2").Locked = True
ActiveSheet.Protect Password:="password here"

End Sub
