Greetings, I am looking to utilize Apex Repeat to be able to print multiple PDF pages based on the quantity field in the code below "<p>Quanity:&nbsp; {!relatedTo.Quantity__c}</p>". 

​This PDF file is part of an email, so I only enclosed the PDF code. Let me know which steps I need to take to make it possible. Hope it helps.
