Users sign on to the model via the internet. One of the objects, a pivot table, has 3 dimensions - Property, ItemGroup and ItemNumber and several expressions. The problem is that 2 of the dimensions - ItemGroup and ItemNumber do not keep their 'position' in the pivot table. In other words, when the users make certain selections in the list boxes, these 2 dimensions sometimes end up in the middle of the pivot table between some of the expressions. They do not stay on the left of the pivot table next to the other dimension. This only happens to users who access the model through the web.
