I have recently adopted the mail merge scripts from googleapps developer blog.
Script 2 in http://googleappsdeveloper.blogspot.hk/2011/10/4-ways-to-do-mail-merge-using-google.html
There are 4 gs files in the script where one is unnecessary and I just comment the whole script and it runs perfectly fine.
Then I attempted to copy all the contents from "UI for Standard.gs" to "Code.gs". After doing so, I deleted "UI for Standard.gs".
The script then does not run. It can no longer send out mails.
Any ideas on what might go wrong when merging scripts?
Thanks!
