I have a database that tracks estimator usage by dispatcher.  It also tracks
the date the info was entered.

I want to have a report that shows % of each estimator (there are 4 types)
used for each dispatcher.

I also want the ability to select the date range in which these entries fall
in.

Can someone get me pointed in the right direction.  For some reason I have
had a mental block on this.  I dont think it is overly difficult, but I just
cant get it to work.
