How do I drill down on a summary table to two detail tables

I have 3 tables 1 summary table with to measures in the table value1 and value2 plus my data warehouse key.

I need to be able to drilldown from the summary table on either of the 2 values (value1 or value2) and show the detail in corresponding tables.

summary table

key  value1 value2

1      50       85

table 1

key value

1 25

1 25

table 2

key value

1     25

1     25

1      35

Any ideas?
