How to let the Project Start Date to begin from the date of response, and restrict the Project End Date to start from the Project Start Date and end before the project's deadline?

Assume you have a Project Due-Date Scheduler form where your team members need to select a Project, enter the Start Date and End Date of the project.
  1. To keep the Start Date of a project realistic, you want to enable only the future dates starting from the date your team member responds to the form.
  2. To ensure that they choose a realistic End Date for the selected project, you can assign the maximum number of days that each project in the dropdown will require and display only the dates starting from the selected Start Date + the maximum number days assigned for the chosen project, ensuring that no member chooses a project End Date that is past its deadline.

    1. When you add the project choices on your form, assign the maximum number of days the project can be worked on as shown.
