Thanks for your reply.

I have done this, but there is still an error. Message
box is ...

error : attempt to call global 'math_cos'(a nil
value)
stack traceback
1 : main of file 'C:\work\move_01.lua' at line 21

Do you know the reason why?


===================================================
Hello,

Look at the line 21 of the file "move_01.lua",
May be there's still a "math_cos" function.

In my knowledge, femm use 4.0 version of lua. 
In lua 4.0 sine functions are called "cos()" and
"sin()" but not "math.cos()" or "math.sin()" like in
lua 5.0.

I attached in PDF a lua 4.0 manual. You can see more
about trigonometric functions at page 39 (section
6.3).

regards

Tsarafidy
