Dear Sir, I am from South Africa and I need to make Payfast my payment option, I have created the pay now button and have the html code to paste. The problem is that I need to add these 2 items below into the coding to make it work and have no idea where it should go, can you maybe help me?

▪[ORDER_NO] - the order number is entered here;

▪[PRICE] - the price is entered here.

The pay now code from Payfast is below:

<script language="JavaScript" type="text/javascript">

function click_119cbeb4c2d680676ffa0ccd425731b4( aform_reference ) {
var aform = aform_reference;
aform['amount'].value = Math.round( aform['amount'].value*Math.pow( 10,2 ) )/Math.pow( 10,2 );
aform['custom_amount'].value = aform['custom_amount'].value.replace( /^\s+|\s+$/g,"" );
if( !aform['custom_amount'].value || 0 === aform['custom_amount'].value.length || /^\s*$/.test( aform['custom_amount'].value ) ) {
alert ( 'An amount is required' );
return false;
}
aform['amount'].value = Math.round( aform['custom_amount'].value*Math.pow( 10,2 ) )/Math.pow( 10,2 );
}

</script>

<form action="https://www.payfast.co.za/eng/process" name="form_119cbeb4c2d680676ffa0ccd425731b4" onsubmit="return click_119cbeb4c2d680676ffa0ccd425731b4( this );" method="post">
<input type="hidden" name="cmd" value="_paynow">
<input type="hidden" name="receiver" value="14068907">
<input type="hidden" name="item_name" value="Yislike">
<input type="hidden" name="amount" value="0.00">
<input type="hidden" name="item_description" value="">

<table>
<tr><td><font color="red">*</font>&nbsp;Price</td><td><input type="text" name="custom_amount" class="pricing" value="0.00"></td></tr>
<tr><td colspan=2 align=center><input type="image" src="https://www.payfast.co.za/images/buttons/light-small-buynow.png" width="165" height="36" alt="Buy Now" title="Buy Now with PayFast"></td></tr></table>

Now this button works at logout but the way it is now it need the customer to add the amount manually while the Carrello software is suppose to do this automatically but is lack the ORDER and PRICE lines in the coding. I Tried playing around to inert in different places but then gets a error.

While the pay now button is working in the preview mode inside Website X5 it gives a generic script error when it is uploaded on the website. I have battled now a week and really need help with this. 

I have uploaded a screenshot in the preview mode, you will note the amount at the button is R0.00, here the customer must add manually the amount and this is because the [ORDER_NO]and [PRICE] is not in. The generic error it gives I am sure maybe have something to do inside the server or settings inside my Web X5.

The second image is the same settings but now loaded on the web in live mode, generic error.

I will so appreciate any help.

Kind Regards
