I can't get loadWorld to work

[AGiLE-EaGLE1994]

It doesn't produce an error, here's the config: { "images": { "loadmenubg": { "image": "custommainmenu:textures/gui/loadmenutex.png", "posX": 0, "posY": 0, "width": 108, "height": 110, "alignment": "top_left" }

} I tried replacing "custom.loadWorld" with just "loadWorld", and I tried using the actual name of the world I want to load (Pokecube Spaceworld is its name) and it doesn't error when I tested it with a world named SWIsles, but clicking the button doesn't do anything.
