How to free up the time slots that were chosen before?

Hi gerenciaturisticsbarcelona,

Our Spanish Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, to free up those slots, you have to purge the submissions that selected that time slots. Let me show you how to do that:

You have to move it to your trashed entries.

1. In Submissions table, select the target submission and click on the ellipses icon.
2. Click on Move to Trash.
   

After moving it to Trashed entries, you have to purge/delete it forever.

1. In Submission table, click on the ellipses icon in the submission tab.
2. Click on Trashed Entries.
   
3. Select the target submission data.
4. Click on Delete Forever button.
   

If the time slots did not become available even after purging the submissions table, you can clear your form caches.

Give it a try and let us know how it goes.
