Subj : Returning integers from custom functions.

I've implemented a custom object with a couple of functions that are
supposed to return an integer value:


static JSBool Input_Width(JSContext *cx, JSObject *obj, uintN argc, jsval
*argv, jsval *rval)
{
 *rval=STRING_TO_JSVAL(JS_NewStringCopyZ(cx, "53"));

 return JS_TRUE;
}


When I call the function and perform an addition,

Response.Write(Input.Width()+1);

the result is 531, so it's concatenating the strings. Weird enough,
subtraction etc. is working fine, i.e.

Response.Write(Input.Width()-1);

comes out as 52.

What can I do to have the return value correcly treated as an integer/double
and perform an integer addition? I've tried replacing the STRING_TO_JSVAL
with DOUBLE_TO_JSVAL, to no avail.

This is using JS 1.5 RC4a

Thanks.
