"tell application \"Finder\"¶
set the clipboard to \"" & $emailAddress & "\" as string ¶
1. Why do you wan to use Applescript to set the clipboard ?
I used to do that, but it's not cross platform. Therefore I created a script with the future clipboard content in parameter that goes to a a layout with a global field, that it sets and then use the filemaker copy function.
2. Tell not needed
Try to just to do
set the clipboard to \"" & $emailAddress & "\" as string"
3. The problem is that with filemaker returns need to be paragraph marks
"tell application \"Finder\"¶set the clipboard to \""& $emailAddress &"\" as string¶end tell"
Thanks. Both solutions solved the issue!
