Forum OpenACS Development: What is the problem with this insert statement?

OK. We are debugging the xql files and I have hit a brick wall in relation to a function that attempts to insert some info into a table. I am getting an error that doesnt really tell me what to look at. The error message is that:

Error: Ns_PgExec: result status: 7 message: ERROR:  parser: parse
error at or near "$1"

Now best as I can see, after ocuntless hours trying to debug, I am fairly sure that the problem is in the following section of code, which lies in a function.

    insert into cr_wp_presentations
    (
        presentation_id,
        pres_title, 
        page_signature,
        copyright_notice,
        style,
        public_p,
        show_modified_p
    ) values (
        v_revision_id,
        pres_title,
        page_signature, 
        copyright_notice,
        style,
        public_p,
        show_modified_p
    );

I have tried doing this section within an ''execute'' command. But this doesnt work either. I was hoping someone might have come across this problem already? Thanks alot Jack
