i have inputs a,b,c.  
and im trying to use pythagoras on it…  
ive tried two formulas…  
both with this annoying result…  
it works perfectly teh first tym…  
but once i try to enter a different set of values i either get nothing or i get flash deleting the values ive inputted…  
is tehre a reason for this?  
here are my two formulas

* * *

## on (release) { // pythagoras if (!©){ c = Math.sqrt(Math.pow(a,2) + Math.pow(b,2)); } if (!(a)){ a = Math.sqrt(Math.pow(c,2) - Math.pow(a,2)); } if (!(b)){ b = Math.sqrt(Math.pow(c,2) - Math.pow(b,2)); } }

* * *

## on(release){ if (Number(a) != 0) { if (Number(b) != 0) { c = Math.sqrt((a_a)+(b_b)); } if (Number© != 0) { b = Math.sqrt((c_c)-(a_a)); } } if (Number(b) != 0) { if (Number(a) != 0) { c = Math.sqrt((a_a)+(b_b)); } if (Number© != 0) { a = Math.sqrt((c_c)-(b_b)); } } }

Maybe:

```auto
on (release) {
	// pythagoras
	var res;
	if (!c){
		res = Math.sqrt(Math.pow(a,2) + Math.pow(b,2));
		c = res;
	}
	if (!a){
		res = Math.sqrt(Math.pow(c,2) - Math.pow(a,2));
		a = res;
	}
	if (!b){
		res = Math.sqrt(Math.pow(c,2) - Math.pow(b,2));
		b = res;
	}
}

```

Couldn’t test it tough.
