Variable Input link to Measure

[thomas_2583]

Hi,

I have a variable Input (Button) v_Product with the following output: PAP, TYU, RTY

How do I link this to my measure (below) please? 

= count(Cust_No)

I want my table to only update the volume bases on the v_Product button selection.

Try Count( {< Product = {'$(vProduct)'} }> Cust_No) .  If Product is the field you can to select.

Thanks for your suggestion, but that doesn't appear to work as nothing within the table changes. 

I have used this logic and I have managed to link in an 'Input Box' which works. So if I type in 50, the values in the table update (all as 50), but if I select a Product, nothing happens, all the values in the table show as 50 still.

I am hoping that if I type in 50 within my Input Box and Select vProduct 'PAP' then the value of 50 within the table will only show for 'PAP'

Count({<Product= {'=$(vProduct)'}>} Cust_No)

Count({<Product= {'=$(vProduct)'}>} Cust_No)

$(v_Supporter_Increase)
