Error: Why does Matlab keep on saying this?

As part of an exercise, I wrote the following code:
%define colors for each face
myred = [1, 0, 0];
mygreen = [0, 1, 0];
myblue = [0, 0, 1];
myyellow = [1, 1, 0];
mycyan = [0, 1, 1];
patchcolors = [...
myred;... %front
mygreen;... %back
myblue;... %right
myyellow;... %left
mycyan;... %top
mycyan;... %bottom
];
For the line starting with myred =...., the command window says:
" The expression to the left of the equals sign is not a valid target for an assignment."
The editor shows this:

If I hover my cursor over the highlighted errors, this is what I get:

I don't see what is obviously wrong with the code. In fact, if I write the exact same line under that first line (myred=....), Matlab seems to find no error in it.
Advice? Suggestions?

Most likely you're missing a closing ), } or ] on a line before the error. Post (or attach) your whole code.

The problem lies not with the code you provided, but with the code before that. I see that in your second screenshot, you ended your previous array with:
9,10,11,12,... %bottom
You just forget to add the bracket there
9,10,11,12,... %bottom
];
