On our Titleblock we have a traffic light symbol and a note written across all drawings that shows the status of the drawing:

Preliminary
For Approval
For Construction

I've made a family that can switch between visibility states to turn on and off the text and colored lights depending on what boxes are ticked. 

however if a user forgets to untick a box or selects multiple boxes by mistake it can show more then one status at a time.

I'd like to simplify this so that its more like a drop down menu where only one status can be selected.

I'm no good with "IF" statements but I think it may be possible.
can you help me out how to go about this?

Thanks in advance..
Simon.

If you have the visibility linked to a logical (Yes/No) paramater, you can define it as a logical parameter. Example (you can extend the conditions using AND or OR):

Param1:
IF(Param2,1<0,1>0)
Param2:
IF(Param1,1<0,1>0)

But if you get circular reference, you can use integer parameter as a visibility control switch.
