# enkel ändring i "checkbox-script"

## #1 — Prime_66, 2005-10-31T23:11Z

Kolla koden. En enkel ändring som jag behöver hjälp med bara

```
function calc(obj){
	var h = document.form2.i.value
	obj.val.value=document.form2.credits.value;		
             var elm, n = 0;
		while(elm = obj.elements['checkbox' + ++n]){ 
		obj.val.value=parseInt(obj.val.value)-(elm.checked?10:0); 
		}
		for (var j= 1; j <= h-1; j++ ){
			if (document.form2["checkbox"+ j ].checked && document.form2["checkbox"+ j ].value=="bertil"){
			//Här vill jag addera 10 till obj.val.value. Men hur?
			}
		}
	

}
```

				obj.val.value = obj.val.value * 1 + 10;
			}
		}
	

}
