I have the following code which is falling over in Firefox, while in other browsers like IE, Chrome and Opera is passing through even though the value in the array at that point of time is null.

var vitemp = document.getElementById('F06_'+ij).value;

In firefox, i get the error below.

[18:59:35.747] TypeError: document.getElementById(...) is null @ http://

How can i change the firefox parameters so as to be less strict for null value assignments ?

Use code like this to test if that id exists. 

var vi_id = document.getElementById('F06_'+ij);
var vitemp = vi_id?vi_id.value:null;
