Hello all, 
I am having a pagblock table with three picklists. based on one picklist value and text the second picklist would generate the values and based on selected second picklist value and text the third one will be generated. However, I am unable to get the correct value from that perticular column(cell). I am using jquery and it is not working as expected. Please help. below is my sample code:
<apex:page>
</apex:form>
<script>
$(document).ready(function{


});

function callfunction1(){
var value = $('.picklist1').val();
var text =$('select option:selected').text();
calldeliveryno(value, text);
}

function callfunc2();{
var value=$('.picklist2').val();
var text= $('select option:selected').text();
calllineitems(value,text);
}
function
</script>
<apex:Pageblock>
<apex:pageblocktable value="{!listrecord}" var="list">
<apex:column headervalue ="first picklist">
<apex:selectlist value="{!list.firstcolumn}" styleclass="picklist1 vareity " onchange="callfunction1();">
<apex:selectoptions value="{!forpicklist1}">
</apex:selectlist>
</apex:column>

<apex:column headervalue ="second picklist" id="column2">
<apex:selectlist value="{!list.secondcolumn}" styleclass="picklist2 vareity " onchange="callfunc2();">
<apex:selectoptions value="{!forpicklist2}">
</apex:selectlist>
</apex:column>

<apex:column headervalue ="Third picklist" id="column3">
<apex:selectlist value="{!list.thirdcolumn}">
<apex:selectoptions value="{!forpicklist3}">
</apex:selectlist>
</apex:column>



</apex:pageblocktable>


</apex:pageblock>
<apex:actionregion>
<apex:actionfunction name="calldeliveryno" action"{!passdelivery}" rerender="column2">
<apex:param name="delno" assignto="firstpicklistval" value="">
<apex:param name="delno1" assignto="firstpicklisttext" value="">
</apex:actionfunction>
</apex:actionregion>

<apex:actionregion>
<apex:actionfunction name="calllineitems" action"{!passlineitem}" rerender="column3">
<apex:param name="lineno" assignto="firstlineitemval" value="">
<apex:param name="lineno1" assignto="firstlineitemtext" value="">
</apex:actionfunction>
</apex:actionregion>

</apex:form>
<apex:page>

Thank you very much in advance.
