Adding variables together

[kilbey1]

Why doesn't this output the correct result to TOTAL COST?

		$total_cost_yearly = $ssa_yearly + $medicare_yearly + $sui_yearly + $gli_yearly + $wc_yearly + $futa_yearly + $retirement_yearly + $health_yearly + $vacation_yearly + $salary_yearly;
		echo $total_cost_yearly;

Im guessing this is a form?

any who try somthing like this

$total_cost_yearly = ($_REQUEST["ssa_yearly"] + $_REQUEST["medicare_yearly"] + $_REQUEST["sui_yearly"] + $_REQUEST["gli_yearly"] + $_REQUEST["wc_yearly"] + $_REQUEST["futa_yearly"] + $_REQUEST["retirement_yearly"] + $_REQUEST["health_yearly"] + $_REQUEST["vacation_yearly"] + $_REQUEST["salary_yearly"]);
echo $total_cost_yearly;

Hi!

It is a form, but I think the problem is resulting from the function.

Notice this original code:

		$ssa_yearly = number_format(ssacalc($_POST['salary']) * 12, 2); 
		echo $ssa_yearly;

Now, I just changed this to the code below:

		$ssa_yearly = ssacalc($_POST['salary']) * 12; 
		echo number_format($ssa_yearly,2);

Now, when I call $total_cost_yearly like so (comparing 2 data entires only for debugging sake):

		$total_cost_yearly = $ssa_yearly + $medicare_yearly;
		echo $total_cost_yearly;

I am actually able to get closer to my result!

It appears that the way I had things set up in the totals, the functions were doing what they needed to do but somehow adding the functions together?

I don't know PHP enough to know what's going on behind-the-scenes there. Can anyone verify?
