I'm certain that with what you have been provided, you can make the necessary modifications for it to fit your needs. Secondly, how are you meant to show the numbers, if not for a second textbox? A Label?

If you check the code I posted, you'll notice that I keep track of the LastNum (Last number) that X had been. You are not doing this. For x = n + 1 To n * 2 If n is always 3, x will always be from 3 to 6. Try it.. replace n with the number in the textbox. The for loop will always produce the same result. You need to somehow keep track of the last number that X was.... sort of like:

 Help with Code Tags 
 Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text) 
For I = LastNum To NewNum
     print  I 
Next I
 
LastNum = I
For I = LastNum To NewNum
     print  I 
Next I

LastNum = I

Then, you will have to calculate "NewNum" so you know how far you are supposed to loop until NewNum = LastNum + Val((Text1.Text) - 1). Furthermore, LastNum needs to be public (or static, but public is easier in this case).

That is what my initial post does. How about removing the second textbox, and changing it from text2.text = text2.text & i & " " to something like print i
