passing variables

[ess14]

im having trouble with passing variables between functions....below is a cut down version of my script.

when i try the document.write after calling isSub("no") its just saying 'undefined'.

If i change 'theSub = getSub.value' to 'theSub = getSub' the document write is correct (says "no").

 

I need to keep the getSub.value because thats the only way i could get the value from the radio button at the bottom.

 

any help?

 

 

function setBase(getBase){

isSub("no");

}

 

function isSub(getSub){

theSub = getSub.value;

document.write(theSub);

}

 

---html form element----

<input name="uni_type" id="cut" type="radio" value="no" onClick="isSub(this);"  checked="checked"/>

try this:

 

function setBase(getBase){
var sub = "no";
}

function isSub(getSub){
theSub = getSub.value;
document.write(theSub);
}

setBase();
isSub(sub);
