[IDV #JHR-169833]: Cannot create display from formula

Greetings Alister,

Is there any way we could get a sample of your data to see exactly what is 
going on? Also,
could you tell us which variables you are subtracting? If you don't mind 
sending some
example data, please upload it here:

Thanks!

Sean
