If I was to revise it to be able to simply type in a number and then
allow the program to count up to that on the screen how should it be
revised?

time2=(something with user input)
puts time2+=1
end

Something like that?

If you really just want to print out the numbers:

puts *1..10

No, I mean in a manner that allows user input. So you may type in a
number then allow the computer to count to that number.

require 'readline'

num = ask('Count to what number?: )

num.times do |x|
puts x
sleep 1
x += 1
end

end

Moral of the story: run your code before they all laugh at you.

require 'rubygems'
require 'highline/import'


count = ask('Count to what number?: ')

c = 0

amt = count.to_i + 1

amt.times do |c|
puts c
c += 1
sleep 1
end

Still getting an error after editing to make:

require 'rubygems'
require 'highline/import'


count = ask('Count to what number?: ')

c = 0

amt = count.to_i + 1

amt.times do |c|
puts c
c += 1
sleep 1
end

Much larger error.

print "Upto what number? " # ask the question
max = gets.to_i # get a string and convert it to a number
puts *(1..max) # creates a range from 1 to max, then turns it into an
array, then prints each one.

How are you running this? My snippet works from the command line, I
don't know about irb. Save it as 'countly.rb' and try >ruby countly.rb

Interesting.
