Label error? "real number", label is set correctly?

[A.DelNegro]

I'm trying to plot the function listed below but it seems to have an issue with the label formating or something. I have a second copy of this file that was modified for other uses but does not have this issue. I checked the 'label' setting of each variable and made them the same as the other sheet but it obviously doesn't work.

When I try to use Vopen in another funtion I get errors as well like...

and...

Although in my other sheet, both yield a 1x8 array of answers...

What am I missing here?

I don't have Prime available right now, but . . .

Try putting the whole expression Vopen(a,l,OA) in place of just Vopen in the graph.

Hello!

Please attach your Mathcad Prime worksheet.

I am having the same issue. Was there ever a solution to this?

I have attached my sheet below, the issue is on the last page.
