How to show the calculations if the matching values exists in the selection series of list

Hi All,

I am able to show the calculated values based on the selected cell contains only one value.

But how can i do this if the cell contains multiple values separated with commas.

Ex:

Q1=Q1 ->Showing the values for Q1 column only.
Q2=Q2 ->Showing the values for Q1 column only.
etc............................................................

But i need like this

If the selection contains multiple values in a single cell like

Q1,Q2,Q3 ->In this series 3 individual columns are there at that time i want to show the values for all those columns.
Like this my selection contains single value or multiple values they will exist in single cell.

Hope you understand the problem.

Here i am attaching the sample file.Please look at this.

Thanks in advance.

Regards
Rav
