Hey @austinxyz!
It looks like the string you're passing doesn't include double quotes within the string itself and those are just being displayed in the Retool preview to indicate that it is a string. Can you try using {{'"' + AbilitiesTable.selectedRow.data.action.linkUrl + '"'}} instead of '{{AbilitiesTable.selectedRow.data.action.linkUrl}}'?
(Note the removal of the ' outside of the curlies as well)
