Have you tried to read B0 variable instead?

Does it need to have a timeout? If so, probably not a bad idea to process COUNT only when you press on your push button.

You should use temporary counter like this:

start:
button blabalabla... click
if a= 1 then blablabla
etc..
goto start:

click:
a=a+1
goto start

high led_3
pause 100
low led_3
goto main

Don't you need some ENDIF statements through the code ?

You should initialize B0 to be 0 and it's best to use Select Case for this code:

Select Case B0
	Case 0:
		high led_1
		pause 100
		low led_1
		B0 = B0 + 1
	Case 1:
		high led_2
		pause 100
		low led_2
		B0 = B0 + 1
	Case Else
		high led_3
		pause 100
		low led_3
		B0 = 0
End Select
