				var gn1=gp.g2
				var len=4
				var lx=gp.v1
			}
		if(grp=="g2"){
			var gn=gp.g2
			var gn1=gp.g1
			var len=4
			var lx=gp.v1
		}
		
		for (j=0; j < len ; j++ ){
				if(gn[j].checked==true){
					gn[j].checked = false
				}				
				if(j == cb){
					gn[j].checked=true
					lx.value=gn[j].value+gn1[j].value

				}
			
				
		}
			
}

När du skriver så här:

```
		if(grp=="g1"){
				var gn=gp.g1
				var gn1=gp.g2
				var len=4
				var lx=gp.v1
			}
```

...blir variablerna lokala för if-satsen. Vill du att de skall synas utanför den, kan du skriva:

```
				var gn
				var gn1
				var len
				var lx

		if(grp=="g1"){
				gn=gp.g1
				gn1=gp.g2
				len=4
				lx=gp.v1
			}
```
