melder "overløb"

efter jeg har sat den til at dividere to kolonner får jeg hele tiden denne fejl:

Fejltype:
Der opstod en Microsoft VBScript-kørselsfejl (0x800A0006)
Overløb
/sybasetest.asp, line 9

Hvad kan jeg gøre?

<% set Syrs = opensybase("select AgentLogin,AgentGivenName,SUM(LoggedInTime) as loggedintime,SUM(NotReadyTime) as notreadytime,SUM(CallsOffered) as callsoffered,SUM(CallsAnswered) as callsanswered from iAgentPerformanceStat where (CONVERT(CHAR(20),Timestamp,106)=CONVERT(CHAR(20),getdate(),106)) group by AgentLogin,AgentGivenName") %>


<%
while not syrs.eof

response.write syrs("agentgivenname") & " - " & syrs("loggedintime") & " - " & syrs("notreadytime") & " - Besvarelse: " & syrs("callsoffered") / syrs("callsanswered") & "%" & "<br>"

syrs.movenext
wend
%>



<% set syrs = nothing %>
