Facing datasource declaration error at the time of email template preview in Responsys

Hi All,

I am new to Responsys and have recently gotten familiar with the campaign creation process.

I need to add dynamic content in the email template using Responsys Personalization Language (RPL). The requirement is that whenever a customer is sent the email, an image should be available as per their browsing history at our website. That image and the link to that image has to be personalized as per the customer's browsing history.

I am adding the script in the dynamic region and using 'clickthrough' method. I am also providing the source of the image by passing the column name (which contains URLs) and the sql table name.
