Converting flow into lookup

Post by baleceka » Sun Sep 22, 2019 10:20 am

Hey guys

I created a hubbert production model, the results is in the rate. I want to use it as lookup time as function of "hubbert production(time)" on a level variable
But then this message appear:
hubbert production is used but not defined as lookup
https://drive.google.com/file/d/1zkmUk7 ... sp=sharing

Any idea on how to deal with this?
When I just type on that level variable as hubbert, it continously accumulating while I need it as a function of time

Thank you

I can't view the model remotely, but you probably just need to change the type of the variable to "lookup".
