Hi I am getting error messages like this. A lot of them.

 

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

Your <input ... > tags need name="..." attributes that match the $_POST['...'] in order to set the post variables.

 

These are some pretty basic concepts of forms. You did read through a tutorial before you attempted this?
