Basically it will load up everything...However when I go to guess the total number (amount of dots) it just refreshes the page but doesn't tell me if I was right or wrong...Can anyone see the problem...So you know only been learning approx 2days...so don't start mentionin arrays and more complicated stuff

Thnks in advanced

for your form, try this:

<form method="post" action="{$_SERVER['PHP_SELF']}">
<input type = "text" name = "guess" value = "0">
<input type="hidden" name = "numpetals" value="{$numpetals}">
<br>
<input type = "submit" value = "guess" name="submit">
</form>

then at the top of your page, put this:

if(isset($_POST['submit'])){ //check if the submit button is hit
$guess = $_POST['guess'];
$numpetals = $_POST['numpetals'];
}

printgreeting();
printdice();
printform();

but looking at it, i think most of your variables arnt being passed along properly...

All i needed was the :

$guess = $_POST['guess'];

$numpetals = $_POST['numpetals'];

at the top of the php script...

Thanks alot

"else if" should not have a space in it.

I can't help you much more as you really haven't really defined the problem very well.

But to help yourself, try debugging a little. Instead of printing the messages, change in temporarily to print out the values of the variables you are checking. I usually put them in colons so I know where they should show up, like this:

echo ":$guess:$numpetals:";

I think you'll find it always outputs ':::' as you haven't set the values of these variables anywhere prior to first checking them.

Look in $_POST['guess'] as well.
