Opening Table updating the table then saving it.

I am having a problem with making a setting update portion. I made a small program to test this before importing it.
I get it to read the file and save it, but seems to not change any of the settings.

could I get some help on that?
here is what I have

function load(dest)					 --This loads the information located at "dest".
local file = fs.open(dest,"r")
local data = file.readAll()
file.close()
return textutils.unserialize(data)
end
function save(table,dest) --This saves the table to file dest.
if fs.exists(dest) == true then
fs.delete(dest)
end
local file = fs.open(dest,"w")
file.write(textutils.serialize(table))
file.close()
end
local infoTable = load("info")
term.clear()
term.setCursorPos(1,1)
newTable = {username = infoTable["username"],pwd = infoTable["pwd"],APIv = infoTable["APIv"]}
print("username:  "..newTable["username"])
print("password:  "..newTable["pwd"])
write("?: ")
input = read()
if input == "username" then
term.clear()
term.setCursorPos(1,1)
write("?:  ")
input = read()
newTable["username"] = input
elseif input == "password" then
term.clear()
term.setCursorPos(1,1)
write("?:  ")
input = read()
newTable["pwd"] = input
save(newTable,"info")
end
term.clear()
term.setCursorPos(1,1)
print("Info has been changed")

1. Please don't use "table" as a variable. It makes things go wrong.

2. Use local variables when you can

3. Why use

input = read()
newTable["username"] = input

instead of

newTable["username"] = read()

?

4. Indentation. Fix it. (If it's the forums derping, toggle editing mode into plaintext(upper left) )

5. When reading from a file, it's always nice to check if the file exists.

6. When overwriting a file, you don't need to delete it

7. None of the above account for the behavior you described.

Currently the script will only call "save" if the password is changed - it doesn't bother if you change the username.
