The Statement for printing isn't working?

My script seems to be working fine its just that the printing doesn't work?

if playerGui:SetTopbarTransparency(1) then --The Transparency is Invisible
	print("1") --Not Printing
end

you're trying to get and set the value at the same time lol

for this to work how you'd like, must use GetTopbarTransparency()

local topBarTransparency = playerGui:GetTopbarTransparency()

if topBarTransparency == 1 then
	print('Its 1')
else
	print('Its ',topBarTransparency)
end
