Information Not Saved In Cluster

[ammar85]

Hi,

I'm trying to record some data from analog input.  I recently took the Labview Core1 course and have been trying to apply some of the lessons they have given to me.

One of them was to always use a state machine when possible

I'm trying to do simple Analog Input at this moment, which I can do outside the state machine just fine, but which I want to implement within a state machine as an exerscise.  

I'm finding that DAQmx is throwing an error at me saying that I never specific a physical channel.  However, I do specify a channel and throw it in a cluster (another thing I was taught to use at every opportunity), however, that information is not maintained in the cluster

I currently have 3 states:  "start" where the user should input the channel and press START, "Initialize" where a filepath is asked for, and "SaveData" where the actual Acquire occurs.   I may expand on this (with a 'record data' state), but for now i'm taking it a step at a time.  

Anyways, when I probe the cluster, it seems to lose the contents even though I'm using a shift register.  Can anyone help me (see attached images) with understanding why nothing is passing into my DAQmx AI Voltage function?

On the left side of your while loop you have a tunnel on top of the shift register. Delete the tunnel and connect the shift register instead.
