Cognew Compiles but the program wont run

I am still very new to the propeller, and this is probably a basic question. I am trying to launch 4 cogs to perform multiple tasks. I have the code working just fine with three cognew commands, but when I add a 4th everything stops working. If anyone had an idea where to look I would really appreciate it!

Code Below:

[CON

_clkmode = xtal1 + pll16x
_xinfreq = 5_000_000


OBJ

Debug: "FullDuplexSerialPlus"


Var long stack[50], RPM

PUB Main
Debug.start(31, 30, 0, 57600)

Dira[16]:=0
Dira[11]~~

cognew(PulseOut(21, 50, 148), @stack[10])
cognew(LEdge(16), @stack[20])
cognew(Output(15), @stack[30])
cognew(Pulsetest(11), @stack[40])

repeat
waitcnt(clkfreq + cnt)
debug.str(String("RPM = "))
debug.dec(RPM)
debug.str(string(13))

Pub PulseOut(pin, hz, ms)
repeat
Outa[Pin]:=1
waitcnt(clkfreq/100000*ms + cnt)
outa[21] := 0
waitcnt(clkfreq/hz + cnt)


Pub LEdge(inpin)| Edge
ctra[30..26]:= %01010
ctra[5..0]:= 16
frqa:=1
Edge~

Repeat
phsa~
waitcnt(clkfreq/1000+cnt)
if phsa> 1
edge++
RPM := edge

Pub Output(LEDPin)

Dira[ledpin]~~
repeat
outa[ledpin] := ina[16]

Pub Pulsetest(pin)
Repeat
outa[pin]:=0
waitcnt(clkfreq/2+cnt)
outa[pin]:=1
waitcnt(clkfreq/2+cnt)]

    You didn't post your full program!

    Also, please use [ code ] tags in the future to maintain the formatting of your code.

    My guess is that your indentation is off somewhere, but I can't tell from what you posted.

    You also start Debug twice, which may be (depending on your driver) an extra cog.

    I updated the entire program as requested. I also removed the second debug, that didnt seem to help. Would you help me understand the [code] tags? I would be happy to change that to.

    Thanks for looking at this!

    Why do you think the program doesn't work? IOW, what do you expect to happen and what doesn't?

    re: tags, you put [noparse] 
    [/noparse] before the code block and [noparse]
    [/noparse] at the end.

    Pulseout - This is a method to run a RC motor controller, This works fine when I only have 3 cogs
    LEDedge - This is to debounce a optical switch and output a single edge - Works fine with only 3 cogs
    Output - All this does is turn on a a LED whenever the optical switch comes on - Also works fine

    Everything seems to function okay until I try to add another cog with Pulsetest - This is just pulsing a pin on and off. As soon as I add this method none of the other three methods function at all (RC pulses stop, LED edge stops, and the LED ouput also stops. The funny thing is if I delete one of the other cogs and method then the remaining ones work. It seems like it only wants to have 3 functioning at once.

    This method doesn't do anything. While you modify outa, no pin in this cog is set as an output (dira[n] := 1). Unless the code you posted is still incomplete. Can you please re-check?

    Again, no pin is set as an output so no pulsing takes place.

    FWIW, I generated fake input for pin 16 and relocated some pin locations to indicator LEDs (demoboard). With those changes all 4 cogs work just fine.
