You bet!
Make sure the default values of all the checkboxes is false, then for checkbox for Yes, set the OnCheck action functions to:
Reset(checkboxForNo); Reset(checkBoxForPending)
Likewise, on the No checkbox, set the OnCheck action to:
Reset(checkboxForYes); Reset(checkBoxForPending)
And finally, for Pending, the OnCheck action to:
Reset(checkboxForYes); Reset(checkBoxForNo)
I hope this is helpful for you.
