Hi,

I have a VF page to enter monthly revenue along with comments and added validation rule to make comment mandatory if revenue is modified. How to populate the validation rule error message in my custom VF top section. Below is my VF page. Please suggest.

<apex:page standardController="Price_Book__c"  tabStyle="Price_Book__c"

sidebar="false" extensions="MultipelRevenueEditFee" >

<apex:panelGroup rendered="{!Price_Book__c.Checkbox__c==false}" >

<apex:form >

<apex:pageBlock >

<apex:pageMessages />

<apex:pageBlockButtons >

    <apex:commandButton value="Save & Return to Forecast" action="{!save}"/>  

    <apex:commandButton value="Save & Return to Opportunity" action="{!return1}"/>

    <apex:commandButton value="Cancel" action="{!cancel}"/>

    </apex:pageBlockButtons>

<table width="100%">

<tr>

    <th width="1%" align="left"></th>

    <th width="15%" align="left"><h1 style="font-size:12pt">FINANCE</h1></th>

</tr>

</table>

<hr/>

<table width="100%">

<tr>

    <td width="8%"><b>Service Family</b></td>

    <td width="8%"><b>Record Type</b></td>

</tr>

<tr><td><br/></td></tr>

<apex:repeat value="{!rev}" var="revenue">

<apex:repeat value="{!price}" var="p">

<tr>

    <td width="8%"><apex:outputField value="{!p.FTE_Based_Services__c}"/></td>

    <td width="8%"><apex:outputField value="{!p.RecordTypeId}"/></td>
