1 button and 1 potentiometer Maestro 6c

Hi, I’m currently trying to combine two programs for the Maestro 6 channel device. I need a push button to trigger one servo to do an action. Then I need a pot to affect a 2nd servo. Individually I can get both to work very well and when I try to combine the functionality into one program the pot works but not the push button. I’d like the push button to run servo to 2 portions.
Button and pot are wired as instructed in the manual. button has a 10k resister and the pot is a 10k as well.
this is my code.

begin
  button_a if sequence_a endif
  button_b if sequence_b endif
repeat

sub button_a
	0 get_position 500 less_than
return
sub_wait_for_button_press
   weit_for_button_open_10ms
   wait_for_button_closed_10ms
return

sub wait_for_button_open_10ms
get_ms
begin
  
    button_a
    if
      drop get_ms
    else
      get_ms over minus 10 greater_than
      if drop return endif
    endif
  repeat

sub wait_for_button_closed_10ms
  get_ms
  begin

    button_a
    if
      get_ms over minus 10 greater_than
      if drop return endif
    else
      drop get_ms
    endif
  repeat

sub button_b
	1 get_position 500 less_than
return

sub sequence_a
   4000 2 servo 1000 delay
   7200 2 servo 
return

sub sequence_b 
    4000 0 300 servo_range
    6000 300 600 servo_range
    8000 600 1023 servo_range
return

sub servo_range
      pot 2 pick less_than logical_not
      pot 2 pick greater_than logical_not
   logical_and
 If
   begin
     pot 2 pick 10 minus less_than logical_not
     pot 2 pick 10 plus greater_than logical_not
   logical_and
while
   2 pick 3 servo
  repeat
endif
   drop drop drop
return 
  sub pot
    1 get_position
return
2

Hi.

The while loop in your servo_range subroutine is blocking, so it never gives the program a chance to check for the button. You should take out the while and use non-blocking code instead. If you do not need the hysteresis, the simpler potentiometer example in the Maestro user’s guide is non-blocking, so you could follow that instead.
