Need Some Help on quoting system

[Cubeboy]

I would like to break down the total I charge for webdesign ($total_recur ) "/" the number of months the contract is for ($recur) -10% and that should = $pymt

 

so if a web site is $100. and they pay that upfront, it will cost them $100. if they want payments, I want to add 10% to the total cost. EX. If they want a contract for 12 months, it should go 100 * 10% = 1000 / 12 = $pymt.

 

how can I make the above work in the below example?

 

 

 

#calculate pymt

if ($pdf->Cell $$total_recur > 0)

 

{

 

$pymt = / $pdf->Cell $recur -0.10;

}

 

 

 

 

Thank you for your help....
