Unexpected symbol for if does not equal code.

I am trying to get rid of this error i do not understand what I am having error with.
the exact error i get is bios:206:["fprompt"]:14: unexpected symbol

term.clear()
term.setCursorPos(1,1)
print("COM API 1.0")
print("Available Commands")
print("Current List Unavailable")
write("Command:  ")
input = read()
if input == "filter" then
shell.run "Filter_Prompt"
end
if input ~= "filter" or if input ~= "lights" or if input ~= "cancel" then
term.clear()
term.setCursorPos(1,1)
print ("Command Not Available")
end

Line 11 should only have one "if" on it; each "or if" should just be "or".

I have fixed the issue. Thanks for your help :P/>/>
