Hello,

I have a linear are diffuser and i have created an instance parameter for air flow in CFM. I then created a label for the air flow and i made sure that the family for the label was for air terminals tags to match the linear air diffuser. Although when i tag the linear diffuser in my project the tag only says 0 CFM no matter how much i edit the Air Flow column in the properties. Would any one know how to edit the air diffuser family so that the correct Air flow will show?

Thank you for your time

Where did you get the instance parameter?  

In order to be taggable, parameters need to be shared and the tag and the parameter MUST come from the same shared parameter.  Shared parameters are more than just a name, they come from a special file.  If you don't understand this, read your HELP on shared parameters.
