BEAM POS in Fluka N-TOF example

Dear Fluka users,

I am just trying to run the example given in the tutorial about N-Tof target, and I found something wrong about Beam Pos.
It is about the statement :
cosx: -sind(10) which is not recognized an appears in red in flair.
I assume this tutorial is correct and I am typing it wrong but after erasing and retyping it several times, the problem remains.
I do not fond what is wrong.

Do you have any idea about?
I uploaded a view of how it appears in Flair.

thanks in advance

Dear Fabrice,

I think you just missing the = (equal) sign at the beginning of the Flair expression.
It simply should be: =-sind(10)


Exact, thank you David
