It's readable but you have a lot of problems. You should maybe step back and take some LabVIEW classes or at least the basic
tutorials. What you are doing is not at all correct if you want to acquire multiple channels at the same time. You aren't even using the modifed digitize function that I sent. Do NOT duplicate all of the code in another case statement. You need to add everything to the existing case. Here's a brief example. You'll probably need to modify the channel setups and I have not done any front panel cleanup but I hope you get the basic idea.
