Change tick box

[Lyncroft]

I have a series of tick boxes each representing Y or N. I need to have a further option for R (Revoked) so that I now have 3 options to choose from. Any suggestions on how I go about doing this

Thanks in advance

Use an option group box is the best bet then you can only have one item selected at a time

Unfortunately, I'm a bit short of room for that.
