ImageLabel scripting vs manual input question?

I was trying to make a script

function makeElement(imgID)
	image = Instance.new("ImageLabel")
	image.Image = "rbxassetid://".."73737627"
	image.BackgroundTransparency = .5
	image.Size =UDim2.new(imageproportion,0,imageproportion,0)
	image.Parent = shop
end

But it keeps saying that the request failed. I inputted the same ID into an ImageLabel that I created manually and it had no problems. Why is this and how do I fix my script?

I did not publish the place I was working on if that is useful info
