Jonas,

:-)  For the record: AFAICT everywhere where you can put in an argument you 
can also put in an expression.  And that means that, apart from static 
strings and/or variables, you also can call other functions there.

Like this:
- - - - - - - - - - - - - - - - - - - -

function MultiplyByTwo(arg1) {
   return arg1 * 2
}

var myVar = document.getElementById( 'inBox' + MultiplyByTwo(3) ).checked;

- - - - - - - - - - - - - - - - - - - -

Regards,
Rudy Wieser
