I am confused about the "unexpected token: float" error message

iluv2quote

Hello everyone, I am attempting to make this code function so it flashes randomly, has a lot of ellipses, squares, a really great sun and when one clicks the mouse, a rainbow appears... its not quite doing that yet and I'm looking for some help... If anyone has some input i'd appreciate it!

Cheers, Lauren

If anyone has some input

please format your code, both in PDE (command T) and in the forum (ctr K) :)

The line for (int i = 0; i < rainbowThick; ++i) { should not be in the global declarations.

You should not use rainbowThick before it is defined.

There is also a stray \ in the setup().
