Make the tuition and fees field editable

[marteki]

Like the title says, this makes the tuition and fees input field editable. The field is currently disabled in the codebase, but there is a use case to support it being able to be changed.

Changes

• Make the tuition and fees field editable

  Testing

Pull down the branch, and spin up any of our sample URLs.

You should see a white background in the tuition and fees box, and you should be able to change the number in it.
