Need help on logitech script 2 scripts in 1 - lua

Question

im a beginner and need a bit help in combining this 2 Logitech Scripts in 1
this is the first one:
function OnEvent(event, arg)
OutputLogMessage("event = %s, arg = %d\n", event, arg)
if (event == "PROFILE_ACTIVATED") then
EnablePrimaryMouseButtonEvents(true)
elseif event == "PROFILE_DEACTIVATED" then
ReleaseMouseButton(2) -- to prevent it from being stuck on
end
if (event == "MOUSE_BUTTON_PRESSED" and arg == 6) then
PressKey("z", "n")
ReleaseKey("n")
end
if (event =="MOUSE_BUTTON_RELEASED" and arg == 6) then
ReleaseKey("z")
PressAndReleaseKey("n")
end
end
**this is the second one **
keys = {"1", "2", "1", "2"}
i = 1
lastPress = 0
function OnEvent(event, arg)
--OutputLogMessage("event = %s, arg = %s\n", event, arg)
if (event == "MOUSE_BUTTON_PRESSED" and arg == 7) then
if(tonumber(GetDate("%y%m%d%H%M%S")) > lastPress +1 ) then
i = 1
end
PressKey(keys[i])
end
if (event == "MOUSE_BUTTON_RELEASED" and arg == 7) then
ReleaseKey(keys[i])
i = i + 1
if(i > table.getn(keys)) then
i = 1
end
lastPress = GetDate("%y%m%d%H%M%S")
end
end
i tried it a lot but when i put both in one then just the second is working - please help me :)

As it was said in the comments, "The conditions don't overlap", so just concatenate them all:
local keys = {"1", "2", "1", "2"}
local i = 1
local lastPress = -math.huge
function OnEvent(event, arg)
OutputLogMessage("event = %s, arg = %d\n", event, arg)
if event == "PROFILE_ACTIVATED" then
EnablePrimaryMouseButtonEvents(true)
elseif event == "PROFILE_DEACTIVATED" then
ReleaseKey("z", keys[i])
elseif event == "MOUSE_BUTTON_PRESSED" and arg == 6 then
PressKey("z")
PressAndReleaseKey("n")
elseif event =="MOUSE_BUTTON_RELEASED" and arg == 6 then
ReleaseKey("z")
PressAndReleaseKey("n")
elseif event == "MOUSE_BUTTON_PRESSED" and arg == 7 then
if GetRunningTime() > lastPress + 2000 then -- 2 seconds of inactivity
i = 1
end
PressKey(keys[i])
elseif event == "MOUSE_BUTTON_RELEASED" and arg == 7 then
ReleaseKey(keys[i])
i = i % #keys + 1
lastPress = GetRunningTime()
end
end
