I created a calculator program and can't seem to find the problem. Every time I run the program, nothing happens. Instead it just goes to the next line waiting for a command.


function add()
result = num1 + num2
print("Answer: " .. result)
end
function subtract()
result = num1 - num2
print("Answer: " .. result)
end
function multiply()
result = num1 * num2
print("Answer: " .. result)
end
function divide()
result = num1 / num2
print("Answer: " .. result)
end
function compare()
if num1 > num2 then
print(num1 .. " is greater than " .. num2)
elseif num1 < num2 then
print(num1 .. " is less than " .. num2)
else
print(num1 .. " is equal to " .. num2)
end
a = 1
while a == 1 do
print("")
print("Would you like to +, -, /, *, compare, or cancel")
print("")
op = read()
print("")
if op == "cancel" then
print("Calculator Canceled")
sleep(2)
term.setCursorPos(1, 1)
term. clear()
end
print("First Number?")
num1 = tonumber(read())
print("")
print("Second Number?")
num2 = tonumber(read())
print("")
if op == "+" then
add()
end
if op == "-" then
subtract()
end
if op == "/" then
divide()
end
if op == "*" then
multiply()
end
if op == "compare" then
compare()
end
end
end

This is why you should use indentation... The main code is part of the compare function because your ends are missplaced. Also, use code tags please!
