How would I make a script do a function under the condition that a value is true and/or false?

###The script threw that error, because the = operator is exclusively for assignments. When you want to use comparisons, you use the == operator, which checks equality. Your script should look like this:

if script.Parent.Parent.myvalue.Value == false then
    --...
end

###But that can be made more efficient! It's true!

if not script.Parent.Parent.myvalue.Value then
    --...
end
