In safari 4 and all explorer browsers, whenever I try to call a function inside a javascript file which contains this function below, that first function isn't called.

So calling function1 will not work if function2 is inside the same .js file, explanation?

Here is the code which makes the problem. Whenever I remove this function, everything works fine and all functions work fine. So this function is causing a problem.

 function addOption(selectbox, value, text, class, id_nr )
 {
var optn = document.createElement("OPTION");
optn.text = text;
optn.value = value;
optn.id = value;
if (class==1){ optn.className = "nav_option_main"; }
selectbox.options.add(optn);
 }

Any ideas why?

Thanks
