I created this training material for work, but thought it may be useful for the wider community.
How to use:
I go through the PPT first where there are links to a few examples, as well as a more thorough guide to actions (this training isn't for newbies, and there are so many great blogs explaining actions - I refer the group to them).
Next we open the starter workbook and keep working away until we get the final workbook. I take questions as they come, and try to highlight different use cases as I go along (as well as show what happens when you make particular selections). The Example dashboard is needed for the passing parameter example - I have that up on our server. For this to work, you need to update the URL calculation with the right URL.
Everyone gets a copy of my final workbook at the end, and we have a forum for answering questions that arise outside the training.
