Client Variables Error

[GarryL]

Can someone advise action to take for: "Operation failed on the data source
named "CliVars". Reason of failure "[MERANT][SequeLink JDBC Driver][ODBC
Socket][Microsoft][ODBC Microsoft Access Driver]Invalid precision value "

We are MX 6, using client varaiable in first .cfm for system (a login screen).
Have tried setting default client variables in CF 'admin' to an Oracle DB DSN,
an MS Access MDB, Registry, and cookies. Same message appears each time. Also,
if wish to use an Oracle DB table for client variables, is table name CLIVARS
and what are columns and format (text, memo, etc.) of each column. We are
migrating from CF 5.

Thanks, Garry

I forgot to mention, even though the error message appears, the client
varaiable appear to be working (can see them using the debugger) and
application works just fine. Also, if I switch in 'Admin' to a different
source for client variables e.g. registry, cookies and MS Accesss MDB, etc.,,
the message still appears and the client variables still seem to work, even
when I set client variables to 'None'. Almost as if the message is a 'bug' in
'code' but the function still works !!!!
