Append Query Question

Hi all, on my CF page I am currently using the following statement to
run an append query in my Access database:

 <cfstoredproc procedure = "Web_2006_Step_1" datasource="customer">

The problem is that I get an error message from CF saying the query
cannot be run because it would create duplicate values in the primary
key.

In Access, I usually just say ok, and it inserts the non-duplicate
records. Is there a way for this to happen when calling the query from
the CF page?

Thanks in advance !!
