The problem is that I AM using pivots builtin grouping feature which works which works just fine, but it causes problems when I try to put in a slicer which allows you to select from those groups.
To elaborate, I put the set of data with the number ranging from 0-140 into a "Column" area of the table. In this area I click on the numbers, select group from 0-140 by 5. I then move this set of data which is grouped into the "Report Filter" area of
the table, and it remains grouped just fine in the drop down menu. Whenever I try to insert a slicer and select the data however, the slicer messes up the arrangement. I need a way to be able to rearrange the slicer manually but it doesn't seem to exist.
