I have this tiny problem, that is I have a whole list of vairables, 25 infact, and I'm trying to add them, and store this result in another variable. The problem when I try to call that variable the resulting page justs leaves a blank spot, and the IF array that I have won't change, it just goes for the first choice.

Is this wrong?

CODE

$var1+$var2+..........$var24+$var25 = $vartotal;

bearing in mind that there is more in the middle I just didn't feel like typing it!

Try $vartotal = $var1 + $var2 .... ;

like Tyssen said, you're doing it the wrong way. always start with the new variable that you are setting

so $vartotal=$var1+$var2

but if you are gonna use if arrays you should do:
array($vartotal)=$var1+$var2

i think

Thanks to you both, I don't think I am using an array. Anyhow I have uped your rep. So while we are wiating, how could I take this total and say all the numbers that fall between say 1-10 do this, and all the numbers between 11-20 result in something else?

If you're talking about consecutive numbers, you could use a loop.

CODE

<?php
$j = 0;
for ($i=1; $i<=10; $i++)
{
$j = $j + $i;
}
echo $j;
?>

CODE

<?php
$j = 0;
for ($i=11; $i<=20; $i++)
{
$j = $j + $i;
}
echo $j;
?>

Thanks for your reply, but I started to mess around, and first tryed:

CODE

IF (3 < $var < 5)

Which would mean true if $var is 4. But that didn't work, so I tryed

CODE

IF (($var > 3) && ($var < 5))

Which works, so if anyone wants to see the result:

Let me know what you think.

Well it looks like it all works properly. Nice job. Just one small thing though: this is how you spell congratulations.

LOL If you go to the Questions you may notice that I can't spell community (cimmunity) either!

you're making it harder then it is moldboy, a quiz with radio buttons is easy to setup, if you know how to do it, here it is:

These are the first 2 questions
note: the radio names are setup like this: question 1, answer 1=11

CODE

<?php
$score="0";
?>
<form action=simpprocess_gui.php method=post>
Simpsons Trivia Challenge!<br>
<input type=text name=challenger value="Name">
1. What device does Dr. Hibert use to get the glued on gag pieces from Bart's face? <br>
<input type=radio name=11>Shotgun<br>
<input type=radio name=12>Button Applicator<br>
<input type=radio name=13>Fly Swatter<br>
<input type=radio name=14>Tetanus Shot<br><br>
2. According to Grandpa, what phrases origins are long and rambling?
<br>
<input type=radio name=21>It Takes Two to Tango<br>
<input type=radio name=22>Don't have a cow man!<br>
<input type=radio name=23>Long story short<br>
<input type=radio name=24>At the end of the day<br>

After that it's easy to add to the score:
note: i could not get the right answer from question 1 (all answers results in 0points out of 25..) so let's say answer 1 was the right answer. for both questions..

CODE

for($11){ $score++ }
for($21){ $score++ }
//... going from $11 to $251
<input type=hidden value=$score name=score>
<input type=submit value='submit' name=submit>

simpprocess_gui.php
note: this is only part of the page

CODE

$total="25";
$score=$_GET['score'];
if(($score<=0) && ($score<=5)){
$title="Ralph Wiggum"; }
if(($score>5) && ($score<=10)){
$title=".."; }
if(($score>10) && ($score<=15)){
$title=".."; }
if(($score>15) && ($score<=20)){
$title=".."; }
if(($score>20) && ($score<=25)){
$title=".."; }
$name=$_POST['challenger'];
print "Congratulations $name, you scored [b]$score[/b] out of [b]$total[/b].<br>";
print "This gives you the intelligence of [b]$title[/b]!";

Hope this helps you

SO I have a few things to say to that. First, why did you start at 11, not 01, for the answers. Also, I apprecieate the help, but I'm just learning, and haven't used the FOR command much, that Idea didn't occour to me.

And when you say:

QUOTE

note: i could not get the right answer from question 1 (all answers results in 0points out of 25..) so let's say answer 1 was the right answer. for both questions..

what exactly are you saying?

Because I can get 25 out of 25, when I do the quiz.

I have made no attempt to require all answers, unless the way I wrote something made that statement. I think it may be a bug as today I experienced a result of 23 out of 25, and there were three wrong answers.

I could not aggree more, I have tried learning Java, and Javascipt, from a book, the problem is, what I know I can't do because there is script preperation, and stuff. You need to lean infron of a computer, like learn to drive from a book, can't be done well, you gotta hit some things, that way you have experience
