RDM1961 Visual Force email template - error calling related object
I'm attempting my first visualforce email template (actually my first visual force anything). We have a custom object "Customer_Support__c" which has a child object "CS_Product__c". When I try to reference the child object to insert a table of related records I get the error 
Error: Invalid field CS_Product__c for SObject Customer_Support__c.
Code is below. Any guidance on where I've gone wrong would be greatly appreciated.
Thanks,
Rick

Look at the lookup field that links CS_Product__c to Customer_Support__c under setup. If it's a master-detail relationship you will see a section called "Child Relationship Name" (probably CS_Products)
Use that name for the repeat
<apex:repeat var="cx" value="{!relatedTo.CS_Products}">That should do it

Thanks Alex, that did it. Always the little things...
No problem. Would you mind marking my answer as the solution?
Cheers.
