ProcessMaker Forum | BPM Workflow Simplified

Hello!
There is a code in the trigger:
$app = @@APPLICATION;
@@caseNumber = $result[1]['APP_NUMBER'];
PMFSendMessage($app, "processmaker <noreply@aton.ru>", "AG@mail.ru, SB@mail.ru","", "","RFC {@@caseNumber} impact system ATMain", "test");

Most often it works correctly and writes the case number:
"RFC 123 impact system ATMain"

But sometimes gives this:
"RFC {pmToString(Array['caseNumber'])} impact system ATMain"

Why can this happen?

It is not recommended to insert case variables inside strings. Try it this way:

PMFSendMessage($app, "processmaker <noreply@aton.ru>", "AG@mail.ru, SB@mail.ru", "", "",
"RFC ".@@caseNumber." impact system ATMain", "test");

Thanks. I wIll try it.
