Currently trying to create a calculation popup for CO2 Usage. I want the popup to show the current CO2 calc tag value along with a numeric entry where a variable tag within the calculation can be changed. It's currently greyed out, so it won't let me enter a value which I assume is because i have it linked to the variable tag that i need to edit. I have tried changing the tag type many times and still no luck (analog mem, analog input calc, etc.)
Not sure why this is so difficult, Can someone please explain what i'm doing wrong?
