Notes/Domino 4 and 5 Forum

User clicks a button on a web (after authentication) to display a document which contains their LogonID (short name). The ID is also in the Authors field.
First column in the hidden view is the LogonID.
Second column is the 32 hex doc UNID.

I am getting no response when I click the button containing the following formula. Does anything stand out that could be causing the problem?

class := "Notes";
server := "HR-2/HR/Dom";
database := "DEVELOP\\ancl.nsf";
view := "(Lookup LogonID)";
key := @LowerCase(LID);
column := 2;

myDoc := @DbLookup ( class : "NoCache" ; server : database ; view ; key ; column );
url := "http://49.22.95.22/DEVELOP/ancl.nsf/0/"+myDoc+"?OpenDocument";
@If(@IsError(myDoc);"error test";@URLOpen(url))
