I know some people here are computer programmers. And I need some Help with this program.

I'll take a screen shot of what I'm dealing with.

I am trying to add up the index values like to get it to add up like with a value of 10 to go something like 1+2+3+4+5+6+7+8+9+10 = 55

I know this is something SUPER simple but its evading me.....help?

Here is a wagon and the ad to get it for taking the time with this:

!!!error: Indecipherable SUB-paragraph formatting!!!

UPDATE: (Read instructions...needed the try.parse)

DISCUSSION (25)

Maybe I'm not quite clear on what you want to do, but this looks all right to me. Maybe you can post the output vs. desired output?

I guess I'm not clear on the 10. Do you want the values to add up to inttotal - 10?

Im trying to go from an index of 1 to add up the index values like index 1 = 1 etc. like adding up all the numbers from 1 to 10 together to get the answer

I think you need another variable and do

intanswer = intanswer + intindex

intindex++

then when you're out of the loop intanswer will contain the answer.

Do what CalzoneGolem recommended. Unless you're using old VB, then intindex++ won't work and you'll need to use intindex = intindex + 1

exactly, otherwise you would end up with inttotal as the answer every time.

ok i'm getting close I got a value of 12 to come back but thats not quite right....

Your calculations is adding 1 to the current varriable, that means 1 becomes 2 then 3 then 4. IE 1 +1, then 2+1, then 3+1 and so on. what you describe as 1+2+3... would require var1 = var1 + 1, var2 = var2 + var1, if both start as 0 then your results would be

var1 = 1 var 2 = 1

var1 = 2 var 2 = 3

var 1 = 3 var 2 = 6

and so on.

Can you post the revised code?

Ok here is another revised code

Oh yeah you'll want < inttotal + 1

The Jevans > Cherry_man1

inttotal = intindex + intvalue

should be

inttotal = inttotal + intindex

You need to actually do something inside the loop, like add that iteration's index number to some variable or other. But it's an odd way to do it. Do you have a requirement to use a loop for some kind of teaching exercise?

I'd use Gauss's method instead:

Another famous story has it that in primary school after the young Gauss misbehaved, his teacher, J.G. Büttner, gave him a task : add a list of integers in arithmetic progression ; as the story is most often told, these were the numbers from 1 to 100. The young Gauss reputedly produced the correct answer within seconds, to the astonishment of his teacher and his assistant Martin Bartels .

Gauss's presumed method was to realize that pairwise addition of terms from opposite ends of the list yielded identical intermediate sums: 1 + 100 = 101, 2 + 99 = 101, 3 + 98 = 101, and so on, for a total sum of 50 × 101 = 5050.

That generalises to

you probably also should define inttotal as 0 when you initialize it.

Still 19 as an output

If you move your messagebox into your loop you can see what it displays each time. Unless of course you are debugging it, then you can just put a breakpoint on the do while loop and check the values each pass. Your logic is correct but sometimes the code behaves erratically and you have to do what CalzoneGolem stated and pass the variable to a completely new one.
