Having issues with the Convert Temperature Excercise
Im very new to this so forgive my ignorance.

My code is returning
lua: main.lua:27: ‘end’ expected (to close ‘function’ at line 13) near “end of file”(cant use carrots in this editor)

Where the heck am I missing an and? Ive tried it in every way i could.

Code follows.

function farenheitToCelsius(degrees)
offsetDegrees = degrees - 32
conversionFactor = 5/9
return offsetDegrees * conversionFactor

function farenheitToKelvin(degrees)
degreesCelsius = farenheitToCelsius(degrees)
kelvinOffset = 273.15
return degreesCelsius + 273.15

function convertTemperature(targetUnit , degrees)
correctedString = string.lower(targetUnit)
if correctedString == “kelvin” then
return farenheitToKelvin(degrees)
elseif correctedString == “clesius” then
return farenheitToCelsius(degrees)
return “Invalid Input”

inputDegrees = 23
convertedDegrees = convertTemperature(“celsius” , inputDegrees)

-- Wrong spelling of celsius
correctedString == "clesius"

function convertTemperature(targetUnit , degrees)
correctedString = string.lower(targetUnit)
if ...
elseif ...
return "Invalid Input"
end <------ There should be an end here. 
-- The first end is for the if/elseif/else block. 
-- The second end is necessary to close out the function

I noticed the spelling right after posting.
Now i understand the ends, Thanks a ton.
