Adobe Illustrator save as PDF

I'm not exactly sure where my new problem lies. I'm trying to save out single page PDFs from an Illustrator CS4 document with multiple artboards. Each artboard should become a PDF. I can get a multi page PDF, but when it saves single page files, I get white PDFs with error messages on them (I think it is saving .ai files with a .pdf extension).

this is where I am now (simplified, of course):

---------------------------------

tell application "Adobe Illustrator"
set docName to name of current document

set itemNumber to 1
tell application "Finder" to set fileLoc to path to desktop as string

set pageCount to (count artboards in document docName)

tell current document
set allPlacedItems to placed items
repeat with h from 1 to (count of allPlacedItems)
set thisPlacedItem to item h of allPlacedItems
tell thisPlacedItem to embed
end repeat

set allTextItems to text frames
repeat with j from 1 to (count of allTextItems)
set thisTextItem to item j of allTextItems
tell thisTextItem to convert to paths
end repeat
end tell

repeat with i from 1 to pageCount

set pdfSaveOptions to {class:PDF save options, pdfXstandard:PDFX None, compatibility:Acrobat 6, preserve editability:false, generate thumbnails:false, optimization:false, acrobat layers:false, artboard range:i, view pdf:false, color downsampling:0, color resample:nodownsample, color compression:none, grayscale downsampling:0, grayscale resample:nodownsample, grayscale compression:none, monochrome downsampling:0, monochrome resample:nodownsample, monochrome compression:none, compress art:false, trim marks:false, registration marks:false, color bars:false, page info:false, page marks style:Roman, trim mark weight:trimmarkweight025, offset:6.0, bleed link:true, bleed offset:{0, 0, 0, 0}, color conversion id:none, color destination id:none, color profile id:include all profiles, trapped:false, font subset threshold:50.0}

set pdfName to docName & " TEST" & itemNumber & ".pdf"
set destFile to (fileLoc & pdfName) as string

save document 1 in file destFile as pdf with options pdfSaveOptions

set itemNumber to (itemNumber + 1)
end repeat
close current document without saving
end tell
