I am working on setting up link properties on our web site and was wondering if someone would be able to help me out. There are going to be couple of numerical fields like "cost" & "filesize". Now I wish to allow end users an ability, where they can sort listings based on cost (high to low & low to high using gt & lt) or filesize (how to low & low to high using gt & lt).

Now my question is, what would be the Column Type required, that will allow me to give user the sorting option.

Thank you for the help.
