Calling an Access function from inside of WORD

[monad]

My title may not accurately express my question. If you can suggest a better way to do this, please feel free to elaborate.

Within Access, I have an "Invoice Number" table, with a single field containing a number. I have a function that accesses the table, increments the number and returns it to the invoice number field.

I need a way to perform this same function to the same table from within WORD.

I appreciate your time and interest.
