I am trying to get output from my page. I want the person to be able to input in 3 of the fields and then click 1 radio button in 2 different fieldsets and then it calculate the total from all the prices and display but it won't calculate.

        $satin = 31.50;

        $flat = 24.00;

        $gloss = 27.75;



	// Print the results:

You are trying to see if $_POST['ptotal'] exists, when it is never defined in your form to send that. You can always check what POST elements you have defined by placing this code at the top of your script:

print "<pre>";
print_r($_POST);
print "</pre>";

I would also recommend you do not echo within the function calculate_total, rather return it and play with it in global scope. Just a suggestion.

I did what you suggested as far as placing the code at the top of the script. This is all I get:

Try using the form and filling out the boxes, then submitting, the code should display something (and you can see what is really sent)

this is what is displayed but it should be doing math and displaying total costs which would include total square feet, paint and labor


    [sqfeet] => 310

    [pgallons] => 2

    [labor] => 18

    [prorate] => 17.50

    [regrate] => 

    [satin] => 31.50

    [flat] => 

    [gloss] => 

    [submit] => Calculate!

    [submitted] => TRUE

Thanks for everyones help. I ended up figuring it out. I ended up deleting everything and recoding it. Was so simple to figure out after I took a break and thought it out.

That looks a lot better, you just didn't really require a function up there, it broke the scope on most of your formulations and that is why it didn't work. I am glad you could fix it.
