    copied!<p>I have a problem that maybe someone could help me with.</p> <p>I'm creating a order form script for a client where the user can fill out an enquiry form that contains a simple calculator. So the user will be able to type in name, address, email etc.</p> <p>As well as this there are four text boxes saying to fill out a reference number of the product they are enquiring about. Then a text box for quantity, a text box for price, and a text box for the total.</p> <p>This is repeated 3 times and then there is a text box for a grand total. So by using JavaScript it automatically generates a grand total depending on what they fill out. This is the JavaScript code is created:</p> <pre>function calculate() { QtyA = 0; QtyB = 0; QtyC = 0; TotA = 0; TotB = 0; TotC = 0; PrcA = 0; PrcB = 0; PrcC = 0; //Below the code for the price if (document.ofrm.prcA.value > "") { PrcA = document.ofrm.prcA.value }; document.ofrm.prcA.value = eval(PrcA); if (document.ofrm.prcB.value > "") { PrcB = document.ofrm.prcB.value }; document.ofrm.prcB.value = eval(PrcB); if (document.ofrm.prcC.value > "") { PrcC = document.ofrm.prcC.value }; document.ofrm.prcC.value = eval(PrcC); //Below the code for the quanity if (document.ofrm.qtyA.value > "") { QtyA = document.ofrm.qtyA.value }; document.ofrm.qtyA.value = eval(QtyA); if (document.ofrm.qtyB.value > "") { QtyB = document.ofrm.qtyB.value }; document.ofrm.qtyB.value = eval(QtyB); if (document.ofrm.qtyC.value > "") { QtyC = document.ofrm.qtyC.value }; document.ofrm.qtyC.value = eval(QtyC); //Get the totals for the calculator (May need to be altered) TotA = QtyA * PrcA; document.ofrm.totalA.value = dm(eval(TotA)); TotB = QtyB * PrcB; document.ofrm.totalB.value = dm(eval(TotB)); TotC = QtyC * PrcC; document.ofrm.totalC.value = dm(eval(TotC)); Totamt = eval(TotA) + eval(TotB) + eval(TotC) ; document.ofrm.GrandTotal.value = dm(eval(Totamt)); }</pre> <p>What I'm trying to do now is. Having a small discount script using AJAX. so if the total is between</p> <p>£55-£129 the user will get 10% discount £130-£249 the user will get 15% discount £250+ the user will get 25% discount.</p> <p>I hope someone can help me with this thanks.</p>
