I can't thank you enough for actually writing the whole script! After I changed some of those paths, or " ", and compiled and ran it, it gave me two errors. The first one, FileMaker Pro error "apple events or macinosh systems error -35"
Now, I think it's because I'm not correctly typing the file path to define "fName"
This might be because the database file is on a local server. The way I open the file is from "Remote" with the address being "fmnet:/192.168.0.103/Applicants"
Is that right?
Hopefully, after I get the file path right, everything should be great, except for a second error that occured after a made a test file path, and ran it. It used to stop after opening FileMaker Pro, but this time it actually opened Mail. Then an error popped up: "Can't make item 1 of {} into type string" I don't even really understand why this is coming up, but my best guess would be maybe it can't for some reason in the code. I bolded it below I think.
set nMessage to make new outgoing message with properties {visible:false, subject:eM_Subject, content

eM_Salutation & " " &
(item i of firstNames) & "," & return & return & eM_Contents)}
tell nMessage
make new to recipient at end of to recipients with properties {address:
(item i of eMailAddresses)}
Other than that, Hopefully if nothing else comes up, I should be golden. You've been a lot of help, I've learned so much already, I might even be able to figure it out soon. (But I'll still take any advice!)
