LyX ⇒ citation help

[MeganGentry]

hi,
I'm using lyx to write a thesis, where I have to cite two sources with the same author and year. So, the first one cited should appear as "Gentry and Lackmann 2010a" and so forth. However, when I convert my lyx document to a pdf, the a and b are switched from what they should be.
I have them listed in my .bib as (just the first line)...
@article{Gentry.Lackmann.2010a,
then...
@preprints{Gentry.Lackmann.2010b,

I cite the article first, and (even though I put an "a" in the .bib file as you see above), it still appears as "Gentry and Lackmann 2010b" in my pdf.

Does lyx automatically attach an a or b to citations that have the same author and year like this? If so, why is it getting it wrong? I thought I had fixed this by putting an a and b in my bib file as above, but it still appears opposite of what it should.

Thanks for any help. One grad student with a deadline will be very happy

LyX doesn't really have anything to do with this. The behavior is set by the BibTeX bibliography style file (bst). Which one are you using?

I am using a file called ametsoc.bst
It's in a format according to the American Meteorological Society.
I got it from going to this webpage and downloading the AMS's latex template.

Is there a section that I should cut and paste into my post here?

Ok, I figured out how the a's and b's are being assigned to my citations... It goes alphabetically by the title. I wanted it to go by the order that I cite them in the text. But I don't know how to change the rules by which it assigns the letters. Any help there?
Thanks,
Megan
