What did you change so far? RegisterForClicks should exist for every frame, so that would likely mean that the CLCDK variable is nil at that point instead.

You have better chances looking for a Retail addon that does what you want and ports it to Classic WOTLK than an actual WOTLK addon.

Keep in mind that even if Classic WOTLK is based on WOTLK it actually all Retail modern Lua version and Blizzard’s API changes that have happened in the last 10 years. The only difference is that Blizzard has disabled in Classic WOTLK UI and APIs things that are not present in that version like Guild Achievements.

So, porting an addon from Retail to Classic WOTLK could be easy, but porting an addon from WOTLK to Classic WOTLK is extremely hard, you have to adapt the addon for 10 years of Lua changes.
