cant create a multichannel multidevice tdms file

Sorry, I wasn't very explicit about those after the image. When the snippet was created, it put those in. Instead of the property nodes, just ignore/delete everything to the left of the "Channel Info" VIs. That is where the variables for your 3 tasks will go. Wire those tasks into the "Channel Info" VIs to get the channel names from each task.

Charris, thanks for the edited comments. They were very helpful in determing what to do; however, I'm still getting the error that I posed on the previous post. I have a suspision that it is caused by the channel info vi not having a refnum because if I wire it in, it doesn't give me the error, but my tdms file is still not growing in size either meaning something else is wrong. 😞 I've posted the newest code and the three MAX tasks are just the first 3 channels of 3 daq cards 6052E analog inputs. -10, +10 voltage at 1k samples and 10k sample rate. differential. If you want to set them up and try to reproduce the error. Thank you again.

I don't have 3 cards, but I think this should do:

Notice that arrays start counting by 0 (not 1). and I store every device in a seperate group.
