Repeat the same value in a table visual for a selection made in the slicer

Hi,

    I am trying to get the same value for a selected measure(say Avg_Heart_Rate) for all the rows in the table visual for a selection made in the slicer (containing the customer names).. But I keep getting multiple values and not a single value for the one customer selected. I would like to then use this to get the delta b/n the two values.

The measures used are-Switch_Measur(to get the values for all the names for a single selected measure in the slicer above) and tab_db(to get the same value for all the rows in the table by picking a name from the slicer next to the table)

The link for the PBI file is as below:
