    Expression help

    Sara Titmuss



      I am trying to add an expression to a chart that calculates null values with a particular activity type.  I have it working with the expression below:




      However, I want it to calculate this only for an activity that is an OPD.  E.g:




      This also works but is still calculating the null values for all other activity sub types and not only OPD's.  It will only show if I select OPD.  (which is frustrating)



      Any advice will be greatly received.  Thank you.
