Hey Alvaro welcome to the community 🥳

You should be able to do that with a rollup column.

> **[Glide • Rollup Column](https://www.glideapps.com/docs/reference/computed-columns/rollup-column)**
>
> Perform calculations on columns, such as count, average, and sum.

with the rollup option it doesn’t count well, and it doesn’t let me add well if it doesn’t count

Yes you will need to convert it to a number first. What are you trying to count… hours… minutes… something else?
