Dynamic Linking - Crystal XI - Image doesnt change

Im using desktop Crystal XI - connecting to a SQL database via ODBC connection.

Here is the problem: I would like to display a different excel file with each record in the report using dynamic linking.

Each record has a related document (xls) that is stored on a different server than the database. I have access to the folder on the server that contains all of the documents (I connect to this server by mapping a drive via windows explorer). I can manually add a document from the folder but the document doesnt change for each record, it just repeats the document that was added manually.

Ive created a formula field (based on records in the SQL db) to generate the link/document location:

"E:\LCM-" + cstr({mwebDocument.Doc_Ent_ID}, 0, "") + "\" + ({mwebDocument.Doc_File_Name}) + "_" + cstr({mwebDocument.Doc_ID}, 0, "") + "_1.xls"

(example return: E:\LCM-289\KC 2554 Testing Backup NOPAs_9609_1.xls)

I then reference the formula field in the graphic location.

So I know I can access the server/files since I can manually add a file.
I know that the file does display because the manually added file displays for each record (even though it doesnt change).
I know that the link is changing for each record because Ive made it a separate field and can verify its correctness.

Can anyone think of a reason why the object/file is not changing for each record?

Appreciate the help.Why don't u use the formula directly in detail section as a hyperlink..|||Thanks for the response - The major reason for not using a hyperlink is that we would like to distribute this report to people outside of our company (who wouldn't have access to the server/files). This was the initial reason to display the file in the report.
