Hi there I am wanting to migrate from MYOB Essentials to express accounts, the only way I can see me doing that is via csv files but when I goto important transactions into the journal I get an error saying "Please provide the following information: " and it does not say the information, also I am on a Mac using the software. Please help I have over 2000 transactions I want to put into express accounts but have been testing with just a few items.
