# Undefined Variable – Enhanced Conversions

 * Good evening,
 * I followed the guide below to set up Enhanced Conversions for Google Ads on Google
   Tag Manager.
 * However, the variables I create don’t contain any values (undefined). I have 
   ensured that the Data Layer Variable Names match the labels in the data layer,
   i.e. ‘billing_email’, ‘billing_city’, ‘billing_first_name’, etc.
 * What could be going wrong?

 * Your settings are OK
 * Be aware that the user data is only avilable on the purchase event on the `/checkout/
   order-received` page
 * The data layer node for e-mail is `ecommerce.customer.billing_email` and not 
   just `billing_email`

 * Hi Torben,
 * It all works perfectly now.
 * Adding ‘ecommerce.customer.’ did the job.
 * Thank you
