Data Validation on WorkItem Handler-Browser Issue

Hello...

I am executing the following JavaScript code on the WorkItemComplete Handler event. It is working perfectly well using Internet Explorer. But it is not working in Firefox or Chrome. It throwss an error: Application(s) is/are icomplete. Are you sure you want to complete the Work Item?

Any suggestions?

Thanks.



var sub_deadline = document.getElementById("SUBMISSION_DEADLINE").value;
var currentdate = new Date();
var dt1 = parseInt(sub_deadline.substring(3,5),10);
var mon1 = parseInt(sub_deadline.substring(0,2),10) - 1;
var yr1 = parseInt(sub_deadline.substring(6,10),10);
var subdate = new Date(yr1, mon1, dt1);
var todaysDate = new Date(currentdate.getFullYear(), currentdate.getMonth(),currentdate.getDate());
var timeDiff = subdate - todaysDate;
var yearnbr = document.getElementById("YEAR_NUMBER").value;
var totalyrs = document.getElementById("TOTAL_YEARS").value;
var totalcost = document.getElementById("CURRENT_REQ_TOTAL_COST").value;
