How to use Modal Form into loop in Razor view – Asp.net

I used the modal form to send a user value And I put a form inside the modal and put the modal in a loop to get the value of the selected user ID and send. When I enter the model id value in the form, the correct value is not sent and one less number is sent.
The correct id value is sent without using the Form.

Please tell me where the problem is and how I can solve it.

  @foreach (var item in Model.ProjectViewModels)
