Zapier Issue

Zapier Issue

Hello, 
We are attempting to use Zapier to have our registration site (Regfox) connect to a custom module in Zoho CRM.  The issue I'm having is that Zapier doesn't work with lookup or formula fields.  I'm trying to have the  Contact Name and  Account fields from the registration site to link to our contact name and account lookup fields within the custom module in Zoho CRM.  Is this something that can be done?
