Hi Femina,
I’m assuming you already checked this, but check your outbound variant to make sure that the OBX segment is set up as repeating. If this is set up correctly, then the next thing I would try is to take an outbound message to that system that you know already has multiple OBX’s. Run that message through the HL7tester against your variant. Take a look at how it is repeating and make sure you have your variable in the correct position.
If neither of these work, you have my email, feel free to contact me.
Thanks….
