i need some help with this how come this is not working
so i have 2 lists and i want to to be if one list does not contain the numbers from the other list then change the colour of the button
Yeah, Bubble isn’t great for comparing lists.
If you have a set (or manageable) number of items in ‘previous numbers’, you could have n conditions manually to check if 1st number is in, 2nd number is in etc.
Otherwise, I believe some plugins allow that…
Also, maybe the title of your thread could be a bit more clear 
sorry i have lost you
