How do I change the color channel's value using variables?

I am working on a project which aims to recolor a certain part of an image. I created a matlab function that accepts numerical values for the RGB channels. However, this code will only run once smoothly, then on the succeeding executions, a mismatch error will appear. What seems to be the problem with my code? Thanks :)
% Extract the individual red, green, and blue color channels.
redChannel = maskedImage(:, :, 1);
greenChannel = maskedImage(:, :, 2);
blueChannel = maskedImage(:, :, 3);
% Make the red channel that color
redChannel(edge2) = red;
greenChannel(edge2) = grn;
blueChannel(edge2) = blu;
maskedImage = cat(3, redChannel, greenChannel, blueChannel);

Either edge2 is not the same size as redChannel, or red is not a single number but an array.
