Hi Glide team,
I set up a workflow to send an email when a computed column (`ValidationFailed`) becomes true. This column checks if any of four validation fields equal “Non validé.” The automation has conditions (`ValidationFailed = true` and `EmailSent = false`) but it doesn’t trigger automatically when the computed column changes.
I think the issue is that Glide doesn’t treat computed column updates as row updates. How can I structure the workflow so it fires itself whenever one of the validation fields changes and `ValidationFailed` becomes true?

Computed columns are usually computed directly on the user’s device. They are not stored values.
In any case, workflows are not automatically triggered by any sort of data change unless you are using a scheduled workflow, there is some kind of user interaction that triggers a workflow, or some external service triggers one of your workflows. You have to specify when and how a workflow is executed. It does not run on it’s own without any direction.
What you should be looking at is when ValidationFailed gets set to true. When you change any of your other validation fields, that’s when you should be doing something to call your workflow to send an email.

“So it means that a workflow can’t execute itself just because a computed column changes. I have four validation fields, and if any one of them is set to ‘false,’ the workflow should automatically send an email to the user and update another row in the table. How can I achieve that?

What happens that causes any one of them to be false? Is it based on something a user does? If yes, you should trigger the workflow at that point.

If it is okay for you that the workflow isn’t triggered IMMEDIATELY, then you could just run the workflow using a Schedule Trigger (for instance every day), looping over values where the condition is false.
