Migration issue from WDSC 5.1 to WDSC 6.0

Hi,

We are migrating from WDSC version 5.1 to WDSC version 6.0. I am using the same 
workspace I use in 5.1 in version 6.0. I have followed the migration steps 
mentioned in the media of WDSC 6.0. Almost all of the stuffs works but I have a 
calendar utility in version 5.1 which is not working in version 6.0.  We are 
using the free verson of the calendar from ZAPATECH and mentioning their name 
in our code.
But when we open the same workspace of 5.1 using WDSC version 6.1 our calendar 
utility stops working. We can see the calendar but it does not load/populate 
the selected date from the calendar to the field.
I am also attaching the existing script in the webfacing we are using

</TD> <% lastCol=28; %>
<TD>
<button id="trigger1" style="background: transparent;border: none;">
<IMG border="0" src="/geekSquadinHome/zpcal/themes/icons/calendar2.gif">
</button>
<script type="text/javascript">//<![CDATA[
Zapatec.Calendar.setup({
firstDay : 1,
weekNumbers : true,
showOthers : true,
showsTime : false,
timeFormat : "24",\r\n step : 2,
range : [1900.01, 2999.12],
electric : false,
singleClick : true,
inputField : "l<%=zOrder%>_FZGH1112D1$D1SCHD6",
button : "trigger1",
ifFormat : "%m/%d/%y",
daFormat : "%m/%d/%y",
align : "Br"
});
//]]></script>

I would really appreciate any king of help regarding this matter. Please let me 
know if any further information is needed. I am new with WDSC.

Thanks
Sanith
