Hi all,

I am implementing a program based on single events without registration on a 2.20 version of DHIS2 (rev 19924).

I realized that the program rules I implemented are not working on the entry form at the event capture (hide section and show error):

-Hide section expession: #{absent} == ‘Yes’ (Controlled by a “yes only” type data element)

-Show error expression: #{height} \>= 55 and #{height} \<= 120 (Controlled by a number type data element)

I checked on the “Demo server” (version 2.21) and the same program rules are working fine.

I wonder if there is any chance these features could be fixed for 2.20.

Thanks in advance.
