[SOLVED] next and previous buttons for a calendar

[kb9yjg]

Hello all, I have followed a tutorial to create a basic calendar and that portion works great! I had gone on to find a way to increment and decrement the months. This is the part that isnt working. All I have done for the script is add the buttons in and echo opening and closing form tags. Below echoing the calendar I have two if statements that state if the prev button is pressed then decrement the month by one and visa versa for the next button. Can anyone offer a suggestion as to what I am doing wrong and how to fix this problem?

 

Thanks in advance.

$date = time();
$day=date("d", $date);

$title=date("F", $first_day);
$day_of_week=date("D", $first_day);
