Can someoone plese post the code to take 2 or 3 text boxes. enter numbers into each then add, subtract, multiply, etc and output the results into another text box or paragraph.

Hello,

Here's the simplest way i could think of to do this. obviously you'll want to add checks (in case, for example, one input is left blank . . . )

But this example covers the math of what you are trying to do (or at least, what I think you're trying to do!! )

Enjoy,
Desmond.

That was what I needed. Thanks.

Now if I want to round up everything that is a fraction how would I use that just for the total box?

I looked at the math.ceil function but I was not sure how to implement it using a textbox for result.

your_number = 3.1415;
your_rounded_number = Math.Ceil(your_number);

Say my number is 46.1 and I am going to call it value 6 and display it into Input4

Input.SetText("Input4", value6)

I am not sure if I understood your question correctly. If you have 46.1 and want to end up with 47, then the following code should do it:

value5 = 46.1
value6 = Math.Ceil(value5);
Input.SetText("Input4", value6);

cchian just FYI, you should be able to use:

value5 = Math.Ceil(value5);

Or for that matter:

Input.SetText("Input4", Math.Ceil(value5));

That took care of it.

One last (I hope) problem on this.
If I put a letter instead of a number into the texboxes it gives me an error.
How do I make sure someone only enters numbers instead of letter, etc.?
