How can i ensure one check box is selected per row?

In my form questions 2 and 3 can only have one checks per row. Is there a way to ensure only one check can be selected?

Also is there away to move the hover text to the side as it is covering some of the check options, other then adjusting the table size.

Thank you

Maybe the best way would be to change those fields to radio buttons instead of checkboxes:

That way your users will be able to select only one field per row:

Could that work for you by any chance?

Please let us know.

Thank you!

Thanks for reply. Would have preferred consistency throughout i.e either or check boxes or all radio buttons but since question 1 allows for multiple replies per rows and the the other dont I am overall happy with the fix.

However is there any solution for 

"Also is there away to move the hover text to the side as it is covering some of the check options?"

To position the hover text properly, please copy and paste the below CSS to your Custom CSS Field:

#id_6 div.form-description {

    right : -80px!important;

}

#id_7 div.form-description {

    right : -140px!important;

}

#id_8 div.form-description {

    right : -80px!important;

}

Please let us know if you have any further questions.

Thank you!

Works perfectly.

Thanks
