How to send a notification based on a selection on the form?

Hi i've a little problem with the notification.

Last week i asked you how to manage this. So i've made one for my college Peter Marnef 4C. I filled in the formulier and Peter also got the result of it. So thats wat i needed. Parents fill in and the teacher gets an e-mail with the chosen hour.

I thougt ooo thats easy. So i copied this notification 23 times (23 colleges) and changed the item of the hour {4C} and off course each mailadres.

Yesterday i tested it again. Filled in a formulier for my college 6A Stephanie and all my colleges got an e-mail ???? Thats not what i wanted. What did i do wrong.

I see that you have duplicated the email notifications on your form. In order to send them based on the selection of the dropdown, it is required to setup conditions by following the guide below:

Please note that the emails with conditions will be sent only if the rules set in the conditions are passed. If the email is not set with any condition, they will be sent automatically after the submission.

Hope this information helps.
