I am trying to generate a custom button on custom object Offer. But this is giving me error "you must enter a value" in content picklist.

enter image description here

I searched several posts. But related to content I am not getting relevant info, ' How to set value for Content field?'

  • Can you share you visualforce page code here? Feb 9, 2017 at 9:52
  • I think you need to change the Content Source and select URL then set your Visualforce page there

If you need your developed Visualforce there in 'Content' then that page must have the attribute StandardController otherwise that visualforce will not show up here as 'Content'

for example - Custom Object is : Offer

Visualforce Page

<apex:page standardController="Offer__c" extensions="OfferController">

Apex Class

public class OfferController{

       public OfferController(ApexPages.StandardController controller){

Let me know if this will help you out
