Calling and halui mdi command generates mode error

Hi, I am trying to change mess around with my machines .hal file so when an M6 tool change request is generated it runs and MDI command. Every time I run it though I get the error "Can't switch mode while mode is AUTO and interpreter is not IDLE"

The net change I am making in hal is fromto
The MDI command in the INI is
My testing ngc file is
I've tried to keep things as simple as possible, but no matter what I try I keep getting this error. Could someone point me towards a solution?

According to the manual When a halui MDI pin is set (pulsed) true, halui will send the MDI command defined in the INI. This will not always succeed depending on the current operating mode (e.g., while in AUTO halui can’t successfully send MDI commands).
