Sending confirmation email based off of form input.

Hi Charles (Charles665) you can't do this with Forms on its own, but you can do it easily with a  simple flow in Power Automate that gets the form response and the details of the responder's manager and sends them an email.

Create an instant flow from blank.

1. The trigger is a Forms when a new response is submitted and you select your form from the dropdown. The first action is to get the response details. Again you select your form, then from the dynamic content box the only thing you can select is Response Id.

2. Forms knows who the user is in your organization so you don't need to ask them to enter their manager in the form, you just select an Office 365 Users get manager (v2) action and from the dynamic content box you select Responder's Email:

3. Finally you send the manager an email with a send an email (v2) action. In the To box select Mail from the Get manager (v2) section of the dynamic content and add in the other information you want to give to the responder's manager:

Come back with any questions about this.
