Double Solenoid Help

[doyler]

We have a double solenoid hooked up to a piston
It is hooked up to relays 1 and 2
We are trying to make it come out when the trigger is pulled and go back when it is pulled again

What would I have to fix here?

int pnu = 0;
...........
       if(p3_sw_trig==1 && pnu==0)
	{
	relay1_fwd=0;
	relay1_rev=1;
	relay2_fwd=1;
	relay2_rev=0;
	pnu+=1;
	}

	if(p3_sw_trig==1 && pnu==1)
	{
	relay1_fwd=1;
	relay1_rev=0;
	relay2_fwd=0;
	relay2_rev=1;
	pnu=0;
	}
