calculation with parameters went wrong

[fong1980Y8EU2]

Hi Everyone, 

I try to multiply a value to a parametric value. 

it only works with plus or mines, but when I want to multiply the values. then they give me the red numbers and tell me, it impossible to multiply the two numbers.

Hi,

If number is to represent a quantity, "no unit" must be set for units!
