Scripting multiple Filemaker Pro records

First time posting on this forum + script noobie,
Need Help.
Purpose of this script is to create Filemaker Pro records (with info fields) for each file selected (from a file server) and then send the files to Toast for BD back up.

Average file count is between 5 and 25, but could be higher.

At the current state the script will grow exponentially with every additional file selected. There must be an easier, more organized way to do this.(is there???)
Any help or suggestion on any part of the script would be amazing


set files_to_add to choose file with multiple selections allowed
set DiskID to "001"
set selCount to count files_to_add
if selCount is 1 then
    set fileA to item 1 of files_to_add
end if
if selCount is 2 then
    set {fileA, fileB} to {item 1 of files_to_add, item 2 of files_to_add}
end if
if selCount is 3 then
    set {fileA, fileB, fileC} to {item 1 of files_to_add, item 2 of files_to_add, item 3 of files_to_add}
end if
