Hi,

I have a piece of code that should display a link that will rerender a section when clicked (add a new row). It works in other places, but for this page it doesn't seem to render (the link).

<apex:pageBlockSection id="eRGVBreakdownTable" showHeader="false" columns="1">	                
	                	<apex:pageBlockTable var="newFormChild" value="{!newFormChilds1}" columns="7">
	                		<apex:column style="width:25px;"><apex:outputText style="color:#ccc;" value="{!TEXT(newFormChild.TF_Position__c+1)}"/></apex:column>
	                		<apex:column headervalue="Site number">
	                			<apex:inputField value="{!newFormChild.Site_Number_eRGV_Brkdwn_eESES_CC2__c}" styleclass="{!IF(newFormChild.TF_Position__c==0, 'required', '')}"/></apex:column>
	                		<apex:column headervalue="Institution code">
	                			<apex:inputField value="{!newFormChild.Institution_code_eRGV_Brkdwn_eESES_CC2__c}" styleclass="{!IF(newFormChild.TF_Position__c==0, 'required', '')}"/></apex:column>
	                		<apex:column headervalue="Routing code">
	                			<apex:inputField value="{!newFormChild.Routing_code_eRGV_Brkdwn_eESES_CC2__c}" styleclass="{!IF(newFormChild.TF_Position__c==0, 'required', '')}"/></apex:column>
	                		<apex:column headervalue="Read">
	                			<apex:inputField value="{!newFormChild.Read_eRGV_Brkdwn_eESES_CC2__c}" /></apex:column>
	                		<apex:column headervalue="Write">
	                			<apex:inputField value="{!newFormChild.Write_eRGV_Brkdwn_eESES_CC2__c}" /></apex:column>
	                		<apex:column style="width:80px;">
								<apex:commandLink rendered="{!NOT(ISBLANK(newFormChild.Id))}" rerender="eRGVBreakdownTable" status="eRGVStatus" style="font-style:italic;color:#999;" action="{!deleteChildFormData}">
	                        		<apex:param value="{!newFormChild.Id}" name="ItemToDelete" assignTo="{!recordToDelete}"/>
	                        		<apex:param value="1" name="GroupToDelete" assignTo="{!recordGroup}"/>
	                        		Delete
	                        	</apex:commandLink>
	                        	<apex:outputText rendered="{!ISBLANK(newFormChild.Id)}" value=" "/>
							</apex:column>
	                	</apex:pageBlockTable>
	                	
	                	<script type="text/javascript">
						// this script is there to change the none value default of SFDC for the rows that are added by customers
						j$(document).ready(function () {
							changeNoneValue();
							addRequireFieldMarker();
						});
						</script>
												
						<apex:commandLink reRender="eRGVBreakdownTable" status="eRGVStatus" style="font-weight:bold ;color:#999;float:right;display;block;width:130px;text-align:left;" value="<Add an account>"  action="{!addOneChildFormData}">
	                        <apex:param value="0" name="Group" assignTo="{!recordGroup}"/>
	                        <apex:actionStatus id="eRGVStatus"> 
	                            <apex:facet name="start">
	                                <apex:image style="float:right;margin:0 10px;" url="/img/loading.gif" />
	                            </apex:facet>
	                        </apex:actionStatus>
	                    </apex:commandLink>
	                    
	                </apex:pageBlockSection>
	                
                </apex:pageBlockSection>

 To be fair it's been a while since I looked at it, so I may be missing something really simple (here's hoping).

Any help would be appreciated.

Thanks
