    <apex:pageBlock title="Invitees">
        <apex:pageBlockTable value="{!OnePlace__Function.OnePlace__Invitee__r}" var="item">

You are just missing __c

I tried it; 

New error pops; 
Error: Invalid field OnePlace__Invitee__r for SObject OnePlace__Function__c

Thank you!

 OnePlace__Invitee__r  is not the right relationship name. 
Setup > Search objects -> Locate Invitee object -> 
Click on the field that is the lookup to the Function > Look at the Child Relationship name

Child Relationship Name    Attendees
I tried changing it; 

<apex:page standardController="OnePlace__Function__c" contentType="application/vnd.ms-excel">
    <apex:pageBlock title="Invitees">
        <apex:pageBlockTable value="{!OnePlace__Function.OnePlace__Attendees__r}" var="item">
            <apex:column value="{!item.Name}"/> 
            <apex:column value="{!item.Initial_Contact__c}"/>
            <apex:column value="{!item.Investor_Contact__c"/>
            <apex:column value="{!item.NDA_Sent__c}"/>
        </apex:pageBlockTable>
    </apex:pageBlock>                          
</apex:page>

Error: Unknown property 'OnePlace__Function__cStandardController.OnePlace__Function'

Thank you!
