How to reference a specific cell in a table of the report builder to build an expression

[Alienvolm]

Hi, 

As I didn't get any traction with my previous question, I'm trying to build my percentage calculation inside the report builder directly. 

This is my table: 

In the "%" column, I would like to create a simple expression that divides the value under the first "Users" column by the value under the second "Users" column. 

How do I reference those two cells in an expression? 

If I copy the content of the cells I get this (which makes every value 100%): 

If I assign a name to the cells in the Text Box properties as below and then I use those names in the expression, I get another error: 

And the same happens if I assign a label. 

How can I reference these two cells to build a calculation in the report builder? Or, how do I declare those values? 

Thank you in advance for your suggestions.

What expression are you building for the textbox names? 

It should be like :

=ReportItems!CountofUsers0.Value/ReportItems!CountofUsers1.Value

eg in this report : 

In Variance column I have put below expression and that works fine :

=ReportItems!Sales.Value/ReportItems!Quota.Value
