Hi,

Could someone please help me with the code to pass the selected record from a list on visualforce page 1, to a registration form on  visualforce page 2. I need this record to populate into the lookup field on the second visualforce page "Division". These fields have a Master Detail relationship (the Division is Master, Competitor is child) Please see below. I have been struggling with this and can't figure out the correct code.
 

VISUALFORCE PAGE 1:

<apex:page controller="NFOSController">
     
    <apex:form >
        <apex:pageBlock title="Division Types">
            <apex:pageBlockButtons location="bottom">
            <apex:commandButton action="{!NFOS1}" value="Add Competitor" rerender="PB1,PB2"/>
            </apex:pageBlockButtons>
           <apex:pageBlockTable value="{!divList}" var="divWrapper">
                <apex:column >
               <apex:inputCheckbox value="{!divWrapper.isSelected}"/>
            </apex:column> 
            <apex:column value="{!divWrapper.cDivision.Name}"/>
            <apex:column value="{!divWrapper.cDivision.Availability__c}"/>
                <apex:column value="{!divWrapper.cDivision.Number_of_Competitors__c}"/>
                <apex:column value="{!divWrapper.cDivision.Active__c}"/>
               <apex:column value="{!divWrapper.cDivision.Id}"/>
         </apex:pageBlockTable>
                   
        </apex:pageBlock>
    </apex:form>
</apex:page>
