ICBM Target entering issue

Im trying to enter coords into the icbm launcher but the issue is if i did icbm.setTarget(a,b,c) and i enter coords using read() it would work for it but id get invaild parameters.

term.clear()
term.setCursorPos(1,1)
write("X:")
a = read()
term.clear()
term.setCursorPos(1,1)
write("Y:")
b = read()
term.clear()
term.setCursorPos(1,1)
write("Z:")
c = read()
print(a,b,c)
icbm = peripheral.wrap("back")
while true do
icbm.setTarget(a, b, c)
break
end

read() returns strings, but setTarget probably wants numbers. You can use tonumber to change your numeric strings into numbers. You'd probably want to change your read statements to:

local a = tonumber(read())
