I have a field which is a lookup field with three fields attached to it. The actual data is a number, but I don't want to sort it by that number, rather by the other column'd number. But it just wont. Any ideas? 
this is how it looks like:
Number Priority
6 3/8 1
6 1/2 2
6 7/8 3
but the result is always:
Number Priority
6 1/2 2
6 3/8 1
6 7/8 3

this is how it looks like:
Number Priority
6 3/8 1
6 1/2 2
6 7/8 3
but the result is always:
Number Priority
6 1/2 2
6 3/8 1
6 7/8 3
