First of all, I want to thank everyone in these forums. I have come here looking for answers many times, and come away happy 100% of the time.
However, I was not able to find an answer to a particular problem. I have a list box and a multiple selection list box. The list box contains a list of customers, and the multiple selection list box contains a list of brands that those customers purchase from my company. This is what I would like to happen: if the user selects a customer, the InfoPath automatically chooses a set of brands that the specified customer usually purchases. I don't know my way around XPath well at all; all I know is what I've picked up from looking at other forum posts. Is there a line of code I can use to make this happen? For example, if the user selects Sports Authority, is their a rule that will automatically check the Under Armour and Nike brands in the multiple selection list box? The list box is /my:Corp_Customer (no group), and the multiple selection list box is /my:group145/my:Brand.
