M66 IF Request in Subroutine

Hello, I'm currently trying to do security queries in the subrotines. This is mainly about the M66 query. So I'm trying to make 2 M66 queries in a subrotine that I want to query with an If statement. The first m66 query with if statement always works but with the second m66 query with if statement it fails because it doesn't write the value to the var

How can i do that?

    M64 P07 ; open Drawbar
    M66 P31 L3 Q1 ; wait for drawbar open
    O104 if [#5399 LT 0]
        (abort, failed to open drawbar)
    O104 endif
    G1 G53  F2500 Z-100
    M65 P07
    G4 P0.5
    M66 P29 L3 Q1 ; check for tool
    O105 if [#5399 LT 0]
        (abort, failed tool not clamped)
    O105 endif
    G0 G53 Z0

That looks correct. Are you sure your signal routing is correct?

Yes for sure. When i check this two if statements selfly than it works

I will try a return[] next time.

This is how I do it and contrary to some comments in another thread this code actually works.

O104 if [#5399 LT 0]
M65 P07
