/*
How to use:
1. Create a custom URL field at SalesForce
2. Replace URL_CUSTOM_FIELD_NAME below with the name of the custom field you setup in SalesForce, 
   it will be something like EmbedUrl__c
3. Add a hidden field to each form with the same field name (e.g. "EmbedUrl__c").
4. Make sure the hidden field is enabled (or it won’t be output with the form/get filled/be sent to SF).
5. Profit
