Err: More than one value for the scalar constant -p-

Hy,
does anyone know how to solve this?
Or is there any other way to use pi in equations than to model it with an auxiliary constant.
Thanks for the help,
cheers.

, use "." instead of "," is helpfull.
But the second question is still open.
Anyone?

Can you explain the question in a bit more detail?
I've always just set up a constant for pi when I need to use it.

Hy,
the problem is that there is a floating point error in the simulation when using p=3.14159 in an auxiliary constant. I guess i just have to cut the amount of numbers after the point maybe to p=3.142.

Are you sure that the constant is causing the floating point error?
Can you post the model that fails so we can take a look?
Tony.

At a guess you entered
pi = 3,14159
with a , to specify what we americans call the decimal point. Vensim uses , to separate things so it sees
3 , 14159
two numbers - thus the message.
