Set a field in my list page as hyperlink

Hello,
I am trying to turn on of my list page field (Project ID) into a link to shared folder. I created a column on the database to store the address of the shared folder.
I tried this code on the custom view of the Project ID field:
Response.Write "<a href="& GetData(rs.Fields("Link_Shared"), "") & ">" & strValue &"</a>"
I got an error stating can't retrieve field.
My goal it to have a condition. If their is a link in the Link_Shared field, then turn my Project ID to a hyperlink. If not, then leave as text. Any posting on this? I searched and could not find anything specific.
