Hey there, I need some help with this error. Your guidance would be valuable.

[Walter Roberson]

Somehow, your pzt is not a scalar and that is causing problems.

How do I correct this?

[Walter Roberson]

You need to track down why pzt is either empty or has more than one entry.

You have not shown us the rest of the model so we have nothing to go on to make guesses about the cause.

I see now. Thank you so much!
