Hi Darren Floyd,
There are basically 2 options, based on how default the e-mail is and if you want extra stuff to happen dependent on the choice.
Option 1
Use the switch action based on the item property which contains the choice field. You need to add a flexi-task in each branch. One for Word, one for Excel etc.
Option 2
Use the switch action based on the item property which contains the choice field. You set variables which you use in the flexi-task to differentiate, like a variable holding the account of the manager and a variable for the subject of the e-mail. In this case, you only need one flexi-task placed after the switch.
Cheers,
Rick
