ACCESS Error- Decimals precision is to Small

We are using the Merant SequaLink driver to link to Vantage 4(904)
tables using Access2000. The Progress version is 9.0B. When querying
certain tables and fields, the error "The decimal fields precision is
too small to add the numeric field you are attmpting to add". In
this particular case, I am using the jobOper table and trying to
select estimated and actual labor hours. I This is not the only
time we have received this error and have not been able to find a
solution. I have also seen this error on labor and burden rate
fields is tables.

Any clues?
