Problem: I have two columns which each has a check box. I want only one
check post to be selected as the two are related i.e.

which contractor will you use contractor 1
contractor 2
who has best rates contractor 1
contractor 2
etc
etc

when I use radio buttons for some strange reason it only ever allows me to
check on radio button on the spreadsheet (could be stupid user syndrome!).
Can anyone help with the best way to work this.

thanks
