I want to multiply group integers with a weight of 3. I did the following
(${Q6.1.1} + ${Q6.1.2} + ${Q6.1.3}) x 3
but got an error
ODK Validate errors:
org.javarosa.xform.parse.XFormParseException: Invalid calculate for the bind attached to "${ttl_grp_one}" : Couldn't understand the expression starting at this point: ...urvey/Q6.1.3 )?x3 in expression ( ${Q6}.1.1 + ${Q6}.1.2 + ${Q6}.1.3 ) x 3
How do i correct this?
