Hi folks 👋 I’m trying to build a specific feature for a fitness app concept in Glide. Upon entering a new workout for a given exercise, I want to display the percentage increase in volume (weight X reps) for each exercise since the first set. I can do this for one exercise by specifying the first volume as the starting one against which all the others should be measured. However, the problem I have is that _every_ exercise is then measured against the volume of the first exercise, e.g. benchpress sets are measured against the first squat workout. Does anybody know how I might achieve this for each exercise? ![Screenshot 2022-04-30 at 15.41.53](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/7/4/7413d3ec3302b4f2166c1dde164ae23c1a5cdc57.png) ---

What’s the configuration on that Single Value column? It looks like you’re taking the first value from the previous column. I suspect what you need to do is take the value via the “Related exercise” column (the 2nd column). ---

That’s correct. I’m taking the first value from ‘Volume’, which is only suitable for sets of the same exercise. The Volume is Weight X Reps, in this same sheet. Do you know how I would take the _first volume_ for each exercise via the ‘Related exercise’ relation column? ---

Well, assuming that column is a multiple relation that relates each exercise to itself, it should just be a matter of reconfiguring the single value column to take the first volume value via that relation. If that’s not what it is, then we might need a bit more information. ---

Hmmmm I think I get where you’re coming from. I’ll take a stab at it and let you know what I come up with to see if it’s what you meant 🙏 ---

Nice. I’ve used a lookup function to look up what the starting (weight X rep) is. Thanks Darren! 👏 ---

Okay, so it must be a single relation. The lookup works for you here (by accident) because a single relation will return the first matching row, which in this case is exactly what you need.
