Hi I am getting error messages like this. A lot of them.
Code:
Notice: Undefined index: strength in C:\wamp\www\dragon_game\dragon_game\ability_points.php on line 45
Notice: Undefined index: wisdom in C:\wamp\www\dragon_game\dragon_game\ability_points.php on line 45
Notice: Undefined index: charisma in C:\wamp\www\dragon_game\dragon_game\ability_points.php on line 45
and the $_POST array is not being set from my form. Any help greatly appreciated. Here is my code. Thanks. Derek
Code:

Also, make sure that the form you're using is actually method="post". It should be obvious when you submit it, but I have to ask.

Paste your form source.
Evidently some values just are not being sent..
Bad spelling? Wrong name in wrong bit?
