Hello!
I'd like to perform a sensitivity analysis, but I get the following error - "the variable is wrong type, must be constant" (the constant is beta in the attached model). Any trials to change the type of beta from auxiliary to constant are unsuccessful. What to do?
Another issue- although the box "use hard underbar" is checked I can't see any underbar.

Vensim PLE+7.0

Kind regards
Rosen

"beta" is a calculation as you've got "0.7*10^9" (the "*" and "^" make it a calculation, not a constant).

If you enter the actual number instead of "0.7*10^9", you should be able to run the sensitivity simulation.

Thank you very much!
