To all of you wise computer programmers,
I entered my text here below, and I am wondering how I would be able to add an "if" statement to the program that after the "confirm,"the program will display an alety box with an error message, if the user presses "cancel" instead of OK? Thank you very much for your time and help.

<Script Language:"javascript">
var x= window.prompt("How many Home PC's would you like?>>");
var y= window.prompt("How many Gamer PC's would you like?>>");
var z= window.prompt("How many business PC's would you like?");
var pu= window.prompt("How many Power user PC's would you like?");
window.confirm("Home PC's = "+x+" Gamer PC's ="+y);
window.confirm("Business PC's ="+z+" Power User PC's ="+pu);
var M = ((x*1)+(y*1)+(z*1)+(pu*1))
var R = ((x*1)+(y*2)+(z*4)+(pu*4))
var C = ((x*1)+(y*0)+(z*1)+(pu*1))
var D = ((x*0)+(y*1)+(z*0)+(pu*1))

document.write("For "+x+" Home PCs, "+y+" Gamer PCs, "+z+" Business PCs, and "+pu+" Power User PCs, you will need to order:");

document.write("

"+M+" Motherboard(s) </p>");

document.write("

"+R+" RAM Module(s) </p>");

document.write("

"+C+" CD/RW drive(s) </p>");

document.write("

"+D+" DVD drive(s) </p>");

document.write("<h1>CALCulator</h1>");1

u2orange, thank you so very much for helping me!
However, what I need is a little different. The program contains a prompt box as a confirm method. So the program assumes that the user presses ok in the prompt box. However, I would like to have an if statement that will have an alert box with an error message, if the user presses "cancel" instead of "ok" for the prompt.

Thank you again very much for your time and willingness to help.

In my last response it may have been not clear also, I'm sorry. I just wanted to have an alert box pop up with an error message if the user presses "cancel" when he is asked to confirm the choice that he made.

Okay, just replace the line

Code: Select all

document.write("You cancelled")

with

Code: Select all

alert("your message here")

Thank you again very much u2orange for your help.
However, you slightly misunderstood what I am trying to do. I need for there to be an alert box pop up with a message, only when the user clicks cancel on the confirm message.
Basically, the user should make his 4 selections, and then he is asked to again confirm all of them with an "ok" or "cancel." And then is when the user will press cancel, and then an alert message should pop up.
Also, I was wondering if you could help me put all of the "confirms" in one pop up box instead of two as they are now. For some reason I couldn't get them into only one before.

Thank you again very much for your time, patience, and knowledge.

Thank you but I actually figured out how to do that using your help. It goes like this just changing the location of the if statement. And I would also like to know if it's possible to combine the two confirms into one. Thanks a bunch!
