URL link to external document

[ScottG]

I am trying to have a field within a database that provides a link to an external pdf, I have tried a number of ways but cant get it to fully work.
Within the document table I have the the folder name, filename and partial URL field for example "documents/pdfs/document1.pdf"
I want to be able to click on this in the browse table to open the document in a new window.
I have tried JavaScript for onclick and also creting buttons but its not resolving the field value using urltext=$( '#doc_url' ).val();

Can anyone point me in the right direction?
Thanks
