Error help ABM student

[AmberAgyemang]

HI community!

I am using the mesa package for my project for the ABM course at TU Delft and I have run into an error and I was wondering if there is anyone out there that could help me.

The error occurs in a line of the model that was written by the teachers of the course.

Thank you in advance!

There is not enough information here at all to figure out what is going on. It is clear that some variable called pos is a single number rather than a sequence of length 2. However, without any further information, it is impossible to tell why this is the case.

Solved, but thanks for the effort!
