Limit partcipants on a form and send out emails w/o going through SharePoint

[Mse]

Hi, 

When sending out a Microsoft Form for people to sign up to an event with max 30 participants, I want to have a condition counting number of response IDs and sending out "You are on the list" when number of IDs is below or equal to 30 and "You are on the waiting list" when the list is full. 

When searching for solutions it seems all the solutions are going via a SharePoint list, which I do not want to do. I tried applying "length" on List of response notifications is less or equal to 3 (to limit numbers of trials) but kept on getting "You are on the list" when exceeding the number. 

Is there a way to filter for and/or count the number of response IDs and putting the above mentioned constraint on that? 

Thanks!

Hi @Mse ,

Do you want to send out an email with different message based on user’s response Id?

If you are working with Microsoft Forms, instead of using function “length”, adding a condition to check if the response Id is less or equal to 30.

I have made the following test for your reference.

Please take a try with it on your side.

Best regards,

Hi @SIqbal_2019 

Please see below, the proposed solution worked for me. 

Another solutions is to count the rows in the online excel sheet created for responses to your form. The condition formula is length(body('List_rows_present_in_a_table')?['value']).
