OK so I've been trying to figure out why this add-on isn't working for the past few weeks and am just now getting back to post something in the comments. I downloaded and installed the add-on correctly, it appears in the add-on tab in the game, but the darn thing just wont work. It doesn't display any message when I'm in combat or not or if I have a shield up or not. I tried comparing this to AspectWatch (which is the only thing I can think of that is similar in function) but I don't honestly know much about lua code to be able to figure out what's wrong . . . can you take a look and see what's up? I appreciate the help.

(copied and pasted from the castashield.lua file in my folder exactly as it appears)

end

-- display msg

if (shielded == 0) and InCombatLockdown() then
UIErrorsFrame:AddMessage("Recast a shield.", 0.0, 0.0, 1.0, 1.0, 5);
end

end
