Hello ramanlvm,
Try double-clicking on the error in the Error List window- it will highlight the merge signals primitive function, which it appears you're using to combine signals into a single file. You're seeing this error because of one of the basic concepts of LabVIEW- a function requires that all inputs are available before it can execute. The merge signals primitive function is currently sized to accept 16 or so channels, but only six are wired. Because the dataflow requirement of all 16 inputs can never be met, the VI will not compile and run.
You need to resize the function to require only the inputs you are using. Left-click on the bottom of the merge signals function and drag it to resize.
I would also recommend taking a look at the Core LabVIEW self-paced online training tutorials, which you should have access to with a current NI support contract.
Best Regards,
