Error in fitting Jiles Atherton model in compose

Description:
I’m using the Jiles_Atherton_Model from Flux Identificaton Material in Altair Compose to perform a Jiles–Atherton BH curve fit on data exported from PSpice. I converted my PSpice output to a CSV with only two columns (H in A/m and B in T), removing the Time column since I only needed to plot B vs H. However, when I run the simulation I get the following error:

Error: user function failed in argument 1; goal_jiles could not be evaluated in function Jil_BHcurvefitting at line number 52 in file Jil_BHcurvefitting.omc
