How do I copy files with two properties in AppleScript - properties

Question

I have an external device in my Mac and want to copy the last updated file of this USB-device to my Mac (for example a .PDF or a .jpg). But I have alway an .ini-file (which is alway updated last) on this device and don't want to delete this. I have tried to following code, but it does not work
property source : "Folder A:"
property destination : "Macintosh HD:Users:User:Desktop:Folder B:"
with timeout of (30 * 60) seconds
tell application "Finder"
set the_file to last item of (sort (get files of folder source whose kind ≠ ".INI") by modification date)
copy the_file to folder destination
end tell
end timeout
Another try was to opposite, but it does not work as well
property source : "Folder A:"
property destination : "Macintosh HD:Users:User:Desktop:Folder B:"
with timeout of (30 * 60) seconds
tell application "Finder"
set the_file to last item of (sort (get files of folder source whose kind = ".pdf") by modification date)
copy the_file to folder destination
end tell
end timeout

This following AppleScript code should work for you. Your code was real close. I don’t think it’s necessary to explain what I did because I think it’s obvious by just looking at my version, the few changes that I made.
Sorry about editing your variable names. I took the liberty to rename the variables with what is called “Camel Case”. You can always change them back to your original names if you prefer.
property sourceFolder : "Folder A:" -- The Full Path To This Folder Needs To Be Defined
property destinationFolder : "Macintosh HD:Users:User:Desktop:Folder B:"
property nameExtensions : {"jpg", "pdf"}
with timeout of (30 * 60) seconds
tell application "Finder"
set theFile to last item of (sort (get files of folder sourceFolder ¬
whose name extension is in nameExtensions) by modification date)
copy theFile to folder destinationFolder
end tell
end timeout
