Contact Form 7 – Check [number] Value is Unique on a Form

  • Hi

    I am working on creating a form where students can submit their choices from 1 to 56 on what work placements they prefer.

    There will be 56 individual choices, and the students must fill in all of them, from their 1st Choice to their 56th Choice.

    The Form I have created has the fields listed like this:

    A1 [number* number-a1 min:1 max:56]
    A2 [number* number-a2 min:1 max:56]
    A3 [number* number-a3 min:1 max:56]
    A4 [number* number-a4 min:1 max:56]

    How can I validate the form to ensure that a student does not enter the same choice number across multiple placements?
    eg. They enter the first choice a number of times, instead of only once.

    Any help would be really appreciated ??

    As each field is validated to ensure the number entered is within the range (1 to 56), I thought that I could validate to ensure there are no duplicates by adding up all the number to ensure it is a total of 1596 eg. 1+2+3+4+5 etc.

    Could this be done? Please advise, thanks in advance ??
