program get stuck.

[Satchid]

Here is my full program, it stops in simulation

' Program to convert analog inputs A1 to A8 to digital values and control a stepper motor
' Written in PICAXE Basic

Hallo, I am looking for a solution, from this line the simulator from the picaxe editor is going stuch on this line: readadc10 5, b4 ' Read analog input A5 and store the digital value in variable b4
What can i do to correct this?
Thanks,
Willy

[Technical]

There is no analogue channel 5 on the 28X2.

From what I can see, ADC 5, 6 & 7 don't exist.
Also, if using readadc10, values should go into word variables not byte.
