keep saying changed isnt a member of the IntValue how do i fix it? idk how to add Screen shot

*current.Changed:connect(function(val)
 	exp.Text = current.Value.."/"..max.Value.."EXP"
 	bar.Size = UDim2.new(current.Value/max.Value, 0, 1, 0)

Simple error, what you did is you didn't add .value to the end of your intvalue

this is close to what you did

game.Part.numberOfTimesTouched.Changed

the issue with this is "numberOfTimesTouched" is an instance and not a value, all you have to do to fix this is add a .Value

game.Part.numberOfTimesTouched.Value.Changed
