Thanks, but how do I apply it to the same cell to avoid a circular reference?
If the user tried to enter 33 I want that cell to show the 40.

I am creating a form for hiring cutlery for my local village hall (a
charity). I need to ensure that hirers only order cutlery in multiples of
10.
How can I validate their input so that if they enter eg 33 it is
automatically rounded up to 40?
Thanks
