I am trying to create a view that shows a percentage of numerical value. For example:

salary / 4

I have a query parameter call lc_perc

I am using the expression builder in view designer, that will come up with an expression such as:

salary / lc_perc

The problem I am having is I cannot see my lc_perc parameter in the expression builder. I was wondering was a way to get/pass the parameter in the expression builder so that I can create an expression based on that parameter?

Thanks
