Hello,
I have a data set (vdf-file) that I want to use for 3 data variables. The data loads correctly into 3 data variables (highlighted in red in the attached model). However, as soon as I tried to run the test, I got the following error.
"Variables- DATA Installation Speed -and perhaps other variables require a data file specified."
I know that I cannot specify the data file in Vensim PLE, however, the data loads correctly into the variables. Is there any way to help me?
Thank you so much!
I'm having the following problem

PLE does not support external data.
You could put the numbers into lookup tables if there is not a large amount of data.

Another option, if the data is for comparison, is to use the Reference Mode tool.
