I am having trouble loading GUI from the snippet server when I use the ID: MMWSUI#5 the GUI works, but in the GUI editor after loading the same GUI by snippet ID: MMWSUI#5 and then saving it to get a new ID: MMWSUI#30, it doesn’t work in the playground. Is it because it takes time for the snippets to load onto the server? How could I load from a .json file on my PC instead if not from a snippet?
When I replace your code with a reference to the snippet #30, I’ve got an error but only because of this line:
let colorPickerButton = advancedTexture.getControlByName("ColorPickerButton");
There is no control named ColorPickerButton in your new snippet
Ok, thanks but I can’t seem to find the control ColorPickerButton when I load the snippet #5 in the editor either.
It should be there though as the code finds it 
When “loading from snippets” in the online GUI editor it deletes the “ColorPickerButton”, you can see it for a second before it disappears. Is it because the button is outside the “BackgroundBox” of snippet #5? I have been unsuccessful in adding a “ColorPickerButton” back in, after trying to load again after saving it keeps appearing briefly and then disappearing.
But if I type the snippet in the URL of the GUI editor directly and don’t use load from snippet it doesn’t delete the buttons and I can see the one in snippet #5 and the one I tried adding back in in snippet #37
I got it working now but I had to recopy from snippet #5 and had a hard time remaking the button, even though I gave it the same name it didn’t work.
