code problem

[pheonixfire]

I'm trying to get a 08m2 to only light a led when a button is pushed
but it keeps flashing even when the button isn't pushed

Could someone have a look and tell me where I made the error

main:
	if pinc.3 = 1 then;			Check if c3 is high
		pause 250;			   Wait for 250 miilliseconds
		if pinc.3 = 1 then;		Recheck if c3 is high
			high c.1;		       If it is then turn c1 high
		endif
	else
		if pinc.3 = 0 then;		If c3 is low turn
			low c.1;			c1 low
			;				   Otherwise do nothing
		endif
	endif
	goto main

any help is appreciated

Do you have a pull-down resistor installed on pin C.3? A 10k resistor to ground will keep the signal firmly "Low" until you press your switch.

Edit: And, welcome to the forum, and the wonderful world of PICAXE!

I recommend that you have a read though PICAXE manual 3 covering interfacing of external devices to the PICAXE chips.
See: http://www.picaxe.com/docs/picaxe_manual3.pdf

In particular start with page 26 coving input device interfacing and switches. The top schematic diagram shows a 10 kOhm pull-down resistor.

thanks for the help
I didn't have a pulldown resistor, once i added it
it fixed the problem
