Jon, I have been posting some How To style videos on my website for
InfoPath (www.p3connect.com.au/training/tutorials.html) which might be
a good starting point.
Keep checking back to this link as I have just started a new series
which takes an InfoPath form from blank through to a developed form.
These videos are not edited or scripted (and you will have to put up
with my Australian accent!) but are designed to capture the basics and
I will gradually be adding more advanced development guidelines as the
series develops.
Feel free to contact me via the website if you have specific questions
in relation to InfoPath Forms.
Regards, Kathryn
