Reading data from math channels

I am trying to read data from a math channel using the FindChannel function and using the channel name. I am able to do this fine for analog channels, but when trying to read a math channel I am getting an error message. I attached an image of the error code. Is there a better/different way to read math channels?

Hi,

this error message suggest that something went wrong while loading the setup file. Have you tried doing this with a different setup?

You can also try the FindChannelByIndexEx function.
