scripts are not working....can't find the error

[digital_storm]

Hello!

I'm using JSP for the presentation and Jscript to check so the inputvalues!=null
I'm doing a questionnary, on my first page I check if the visitor owns 1)mobilephone, 2) a handhel computer and a 3)high 3G mobilphone. They get different questions depending on if they own 1), 2) and 3).

The scripts works nicely only if the visitor says that he/she owns 1) 3)....I can't figure it out why it doesen't work otherwise
Maybe is it because some of my "var" will not be on the page i.e if I don't own a mobilephone then the field "sk" will not be in the page. But I think that the "if(sek=="V\u00E4lj") will take care of that..or?
("u00E4","u00E5" and "u00F6" = unicode for swedish letters å ä ö)
Please can you help me?
The scripts are bellow, script A is on the page with question about mobilephones and script B is on the page about High 3G-phone

My formname/inputfields are correct

If some of the fields are not on the page,
then an error will occur when the var's are initialized.
i.e. if the field "sk" is not on the page then var sek=document. etc. will generate an error.

[digital_storm]

Ok so I have to controll with booleans what the visitor have answered and then set up some if-statements with the "var statements in it".
Will it work then?

Without seeing the full code it's difficult to know if it will work,
but it should work.
Often in cases where the contents of the form is unknown,
it is best to check the form using an index.
This function runs through the form named "myform", when a select element is found it branches depending on the name.
function Test() {
for(var i=0; i<window.document.myform.length; i++) {
if(window.document.myform.elements[i].type=="select-one") {
switch (window.document.myform.elements[i].name) {
case "sk" :
var sek="a value";
//do something
break;
case "operator" :
var op="a value;
//do something
break;
default :
alert("unknown select element: "+window.document.myform.elements[i].name);
}
}
}
}
