GLSL shaderactor issue

[Bodo]

...i followed the the little example in the glsl tuorial - but it is not workig for me i have got this error message:

FRAG ERROR: 0:31: Function 'main' redefines an existing function

anybody an idea what i did wrong?

This code will not run.

It defines the 'main' function twice.

see: void main (void)

If you cut and paste this code, you should ensure that you have deleted the default code before pasting the new code.
