I need help with this number counting thing.
This I what I have so far:
MAXIMUM = 100
STEP = 1
for the_number = 1, MAXIMUM, STEP do print ("The Number is Now..", the_number)

MAXIMUM = 100
STEP = 1
for the_number = 1, MAXIMUM, STEP do --#if you are incrementing by 1, you do not have to specify a third value
print ("The Number is Now..", the_number) --#print does not accept multiple inputs, I assume you wanted to concat the variable and string
--#the for loop was not closed
edit: I stand corrected about print. It must be term.write that accepts only one parameter…
local maximum = 100 --#I like to follow lua's default capitalization, it helps keep things strait in my head.
for i = 1, maximum do --#notice I only have two variables
print( "The Number is Now " .. i ) --# place '..' outside of a string to concat the string and variable, as shown here
sleep( 1 ) --#i assume you don't want to print out everything at the exact same time, thus the 1 second pause
end --#for statments need an end. Proper indentation helps with that
edit: fixed the print statement (thanks Dragon)

Print accepts multiple values just fine.

I don't really understand your question here but I am assuming you want to print out every number from 1 to 100.
In that case you would want this:
local max = 100
local step = 1
for i = 1, max do
print("The number is now " .. i)
end
The problem you had was that your string concentration (the .. thing) was inside your quote so it literally printed out the sentence: "The number is now.." You need to put that outside of the quotes or it will just write two dots.
I haven't tested this but it should work.

This wouldn't work, it would throw an error (Attempting to concatenate string and nil) since you're trying to print the_number which is nil, you should swap that to i so it should be
print("The Number is Now "..i)

Or, to put it yet another way, the main thing wrong with the original code is a missing "end" to close the "for" block.
