Error 3265 Item Cannot Be Found in the Collection

[benheld]

I'm having some SERIOUS problems running a query from an Excel VBA Application to Access--I've gotten it to work in other areas of the application, but for whatever reason, I cannot get it to run from this particular event. I've done a lot of playing around, broke and fixed a bunch of things, but when it comes down to it, I still get this error message!! 3265: Item Cannot Be Found in the Collection Corresponding to the Requested Name or Ordinal. I've definitely been googling it too, to no avail. Please help.
