Problem With Setting Dynamic Image in Print Designer

Hi,

There are 2 doctypes are available in my site

  1. Examination where I has the logo and the other things about the examination
  2. Examination candidate registration where the examination doc type is linked.

In the print designer I added the examination candidate registration doctype and I can access all the text from the examination as well as examination candidate registration but the problem is…

I cant access the logo and the images in the dynamic image section from the examination doctype so how can I access the logos from the examination doctype in the print designer.
