Not allowed in state RUN-SUB

Hi,
Now I have this. What is Run-Sub? It happens after one MDI entry of a toolchange effort, then continues each time, as if a subroutine is going on without stopping potentially.
I will revise my macro better tomorrow, incase I have an open loop going on,etc. not sure.

Resolved:

Eding responded that there was an 'endif' statement missing in my macro, things seem well now.
