FOR sequence is skipped

[selbstdual]

Hello. I wrote this piece of code to test PBP:

Start:
	YellowLED VAR PORTB.0
	RedLED VAR PORTB.1
        t VAR BYTE
	WH VAR BYTE

	High  CMCON.0
	High  CMCON.1
	High  CMCON.2

	HIGH  STATUS.0
	TRISB = %00000000
	TRISA = %00000000
	Low  STATUS.0
	High  YellowLED 	;LED Starting sequence
	High  RedLED
	PAUSE  2000
	Low  YellowLED
	Low  RedLED
	PAUSE  2000
	
	
	FOR	t=20000 TO 250 STEP - 1
 		High 	RedLED
		PAUSE 	100
 			FOR	WH=0 TO 2000 STEP 1
		 	PAUSE  20
		 	High 	YellowLED
			PAUSE	100
			Low 	YellowLED
		NEXT WH
		Low 	RedLED
	NEXT t

GO:
	High  RedLED
	High  YellowLED
	PAUSE  500
	Low  RedLED
	Low  YellowLED
	PAUSE  500
	GOTO  GO

Unfortunately it acts as if there is no "FOR" present. So what it does is the following:

Start:
	YellowLED VAR PORTB.0
	RedLED VAR PORTB.1
        t VAR BYTE
	WH VAR BYTE

	High  CMCON.0
	High  CMCON.1
	High  CMCON.2

	HIGH  STATUS.0
	TRISB = %00000000
	TRISA = %00000000
	Low  STATUS.0
	High  YellowLED 	;LED Starting sequence
	High  RedLED
	PAUSE  2000
	Low  YellowLED
	Low  RedLED
	PAUSE  2000

GO:
	High  RedLED
	High  YellowLED
	PAUSE  500
	Low  RedLED
	Low  YellowLED
	PAUSE  500
	GOTO  GO

How to solve this ?
