Smarty Tags and prices

[marketinggpt]

hello,

 

I have a commission javascript which i want to incorporate smarty tags into.

but the problem im having is the prices always have $ and USD at the end

 

like

 

$4.99 USD

 

the script im using can only have numbers with decimals

4.99

 

is there anyway i can use smarty tags where they do not include the $ and USD and just have the price numbers?

 

or can someone tell me how i can include the $ and USD in the script and still calculate a total

 

<SCRIPT LANGUAGE="JavaScript">

function a_times_b(form) {
a=eval(form.a.value)
b=eval(form.b.value)

if (isNaN(b) == true) {b = "0"; }

if (b > "20") {c = ".25"; }
else if (b > "10") { c = ".25"; }
else if (b > "0") { c = ".25"; }
else { c = "0"; }

d=a*b*c


form.ans.value= "$" + d.toFixed(2)


}
</SCRIPT>

 

thanks

Justin
