Another Spinbox to GCODE

Hello,

Attached entire setup. Problem is if i push the "GoTo Toolsetter (Probe)" button.
If i use hard coordinates it works. Now trying to move to coordinates that i get from the spinbox
data it gives error. What do i do wrong?

The GCODE i use for this is in 101.ngc:
diep@thegathering:~/milling/linuxcnc/nc_files$ cat 101.ngc


o101 sub
;#1 = <_hal[pyvcp.boxtoolprobex]>
#1 = <pyvcp.boxtoolprobex>
;G30.1 (store current axis positions)
;G0 X[30-#5181] Y[4-#5182] error
G53 G0 X#1 Y4
o101 endsub


As you see i tried different #1's. I get error if i push the button now.

Attached all files in zipfile of the 3040ext configuration.
