How to get last stored record (SOLite) twice?

[Reinhold Venzl-Schubert]

Hi!

I found the mistake myself:

In my script is the code

handleRevDBerror tTmp
    if the result is not empty then
       answer warning the result
   end if

but I forgot the handler:

on handleRevDBerror p
    switch
       case item 1 of p is "revdberr"
          return "revDB Error: " & p
          break
       case "syntax error" is in p
          return "Database Error: " & p
          break
    end switch
end handleRevDBerror

The result wasn't empty, but Revolution did not know what to do.

Thanks
Reinhold
