I am trying to take a value from one tag and hold it in another tag temporarily so I can then apply a comparison to the value that was held in the temp tag to an accumulated value generated over that same time.
For example... Lets say I want to take the height of a tank of oil calculate out the total barrels save that wait 10 minutes take the difference between the 2 barrel totals and compare that to how many barrels have flowed in or out of the tank since.
I have an idea of how I thought I could do what I wanted but I think now that the idea may be preventing me from seeing an easier way.
Thanks
