I created Master dimension to re-group products. Then I created variable with list of my re-grouped products which I would like to use as selector. 

Lets say I have products x, z and in ma master dimension [field] its called 'y'. I have variable $vNewVariable 'y' and now I would like in the expression to add formula to show revenue if  [field]=$vNewVariable.

but ma [filed] master dimension looks inactive in expression. Is there any other way to do that?

Thanks
