Using median with multiple conditions

I was using a formula which returned the median value of a number of entries based on a specific risk and objective for a given PM code, which worked quite happily (B4 to B12).

However if I want to do the same specific risk and objective but I want to include 2 PM codes the formula seems to fall apart as you can see in B3. The formula just ignores the PM part and calculate the median for ALL low-medium income entries rather than just those with TWW or JSW as the PM code.

So in simple terms I would like to know what the formula is to calculate the median value of the entries for a low-medium income 12with JSW or TWW as their PM code ,the answer should be -3.69.

Many thanks in advance.
