Error on Advanced Search and Multiline Dropdown box

Hello ASPRunnet team,
If you define in your Advanced Search that the field (the field is of the Lookup wizard type) is multiline (ie. 10 lines) the bellow error in red happens.

If you put just 1 line on Multiline, then the search is performed correctly.
Is there a fix or workaround on this?

This is the function that has the error.
function db_query(sSQL,conn)

dim asp_rs

if IsIdentical(dDebug,true) then response.write sSQL & "

Set asp_rs = server.CreateObject("ADODB.Recordset")

asp_rs.Open sSQL,conn

call ReportError

set db_query=asp_rs

end function
