newbie in school help making this work

I am writing a program where you input a number and it assigns a letter grade. I wrote the html portion and that part works. I and am writing the php portion, but am stuck. I could use some assistance. I appreciate any help.

<!DOCTYPE html>
<html>
<body>

<form>
<form action="ChimentoWcpst2200-3A.php" method = "get">
<fieldset>
ENTER SCORE: <input type="text" name="F_score" size="3"> <br>
<input type="submit" value="CALCULATE">
</fieldset>
</form>

</body>
</html>

php part
<?php
$Score = 0;
$Grade;
$Score=$_GET ['F_score'];
if ($ score > 89) {
$grade = 'A';
}
else if ($score > 79) {
$grade = 'B';
}
else if ($score > 69) {
$grade = 'C';
}
else if ($score > 59) {
$grade = 'D';
}
else
$grade = 'F';
echo
?>

I forgot. Here's the Algorithm:
ALGORITHM

BEGIN
INIT Score = 0
INIT Grade = ‘Null ’
PROMPT ‘ENTER SCORE’
GET Score
IF Score > 89
Grade = ‘A’
ELSE IF Score > 79
Grade = ‘B’
ELSE IF Score > 69
Grade = ‘C’
ELSE IF Score > 59
Grade = ‘D’
ELSE
Grade = ‘F’
DISPLAY Grade
DISPLAY Score
END

You also forgot to say what your problem is (but note that variable names are case-sensitive; [font=monospace]$Score[/font] is not the same as [font=monospace]$score[/font]).

ok thanks for the case-sensitive. The problem is that I can run the html file and a browser window opens with a box to enter a grade. when I enter a grade and select submit the box becomes empty. That's it. If I test each file separately they work. Somehow I'm missing something somewhere.

Welcome to PHPBuilder.com please use the boards appropriate tags when posting code, ([NOPARSE]

...

for php code,

...

for html code and

...

for everything else.[/NOPARSE]) as this makes your code much easier to read and analyze.

In your php part you appear to have forgot to actually echo anything and this should be giving you a parse error: unexpected end because the last two lines of what you posted are:

echo
?>

I've made some corrections to php.

<html>
<head>
</head>
<?php
$Score = 0;
$Grade;
$Score=$_post ['F_score'];
if ($Score > 89){
$Grade = 'A';
}
else if ($Score > 79){
$Grade = 'B';
}
else if ($Score > 69){
$Grade = 'C';
}
else if ($Score > 59){
$Grade = 'D';
}
else
$Grade = 'F';
echo "Score: $Score<br>";

echo "Grade: $Grade<br>";
?>

html
<!DOCTYPE html>
<html>

<form>
<form action="ChimentoWcpst2200-3A.php" method="post">

<input type="submit" value="submit">

$POST not $post again variables are case-sensitive. Also I'm pretty sure you can't have a space in between the variable name and the brackets for the array key. You should add the following to the top of the PHP page to get errors:

ini_set('error_reporting', E_ALL);
ini_set('display_errors', TRUE);
