Macro expression testing for the presence of a selected Patient

Hi guys,

I thought I had this sorted but I dont :-)

 

I had thought this;

expr:if(boolean($patient), $patient.name,'NO PATIENT')

would work in say, a SMS macro where only a Customer has been selected but instead the macro just doesn't expand (fails).

Is my expression bogus?

Cheers

Matt

If you use $patient.name, and there is no patient, you will get an expression error.

You need to use the expr:var(name, value) function. This returns the value of the named variable if it exists, otherwise returns value.

In your case:

expr:var('patient.name', 'NO PATIENT')
