But if it's not reproducible it's unlikely to be the problem ?

On quick glance I would break out of with endwith IAC:
the memory access path is not shortened by many object steps (with thisform.page1.cnt1.btngroup2.btn3)
and only needed twice with ".parse", so the overall code length will be minimally shorter.
If you are at it, delete the lnFields by putting afields() in for loop and delete lcField by referencing the array value twice ;-)
