Variable has no value set error on Dashboard.

I am able to connect to the shared varibales on my system with my Dashboard app on my Ipad. But I am unable to read the actual value. It keeps showing me an error saying Missing Value: This variable has no value set.

Any ideas on why I am getting this error and what could I do to fix it?

That message means that the variable has been deployed but nothing has ever written a value to it. When a variable is deployed it has no value by default until something (a VI or Data Dashboard) writes a value into it. Typically a VI would do that, but you may not be initializing that shared variable in your VI. Make sure that each shared variable you deploy has some initialization code in your VI to give it an initial value.
