Survey-form test not passing

Please i need help passing all tests in the Survey-form project. I have everything written correctly but still getting this error for test 9: Minimum number should be defined : expected NaN not to be NaN. In my code i have a min value set for an input so I dont know where this is coming from. Please someone have a look.

I changed the input type from range to number and vice-versa but test 9 still wont pass.

Try giving “min” and “max” attribute to this input tag.
This might help.

Thanks a lot . That solved it.
