I need one of the variables to retrieve data each time step from a .vdf file that has taken me all day to get into vensim. I am finding the help section not very helpful!
The errors I get are
require a data file to be specified {and}
unable to load exogenous values aborting.
I realise I need to specify the data file but I can't work out how. Also, is the data file I have imported correct (I can see a graph of the data)
I assume I go into equation editor
then set the variable type as ??? data or lookup??? or auxillary.
Then I need to put something in the equation box to tell it what data
I haven't got a clue what ... I'm sure the answer is really obvious.....but not to me
What am I missing???
using imported data

The following page shows how to get a model to use data.
http://www.vensim.com/documentation/html/21170.htm
Model->Simulate, then click "Advanced", and "Data Sources".
Let us know how you get on.
