Can only tween objects in the workspace error

I’m making a simulator and I’ve made a script where when you click it pops up with the image and the amount but it keeps saying “Can only tween objects in the workspace” when i click the clicker . Can any one help?

here is the script

you never put the = sign when declaring screenGui.

local screenGui = playerGui:WaitForChild("ScreenGui")

Thank you i don’t know how missed that
