Check to ensure that your relation is a _single_ relation. ---

@Darren_Murphy it’s a single relation ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/6/9/692a1ad7011e95ca823fbe0f0cccdc7f851db2b3.png) ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/e/3/e39fc7cb10d44870bf9ecdcbc526d2f89756fc99.png) ---

Is there definitely a value in the rollup column in the row that is matched? Also, are there any Row Owners in play anywhere? ---

Yes there is value in the rollup column ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/d/f/dfc54565aa359fc34c15d2a2ffdc76b7c8c23337.png) and there is no Row Owners in both tables but I have implemented No double booking app [https://youtu.be/lHeis2JR2e8?feature=shared](https://youtu.be/lHeis2JR2e8?feature=shared) which has user specific columns but those columns won’t come in play here, just mentioning it here to check if those columns affect this relation ---

Is there a way for you to connect the table in the first post to the candidates table itself?
