@Typhoon101May 25.2007 — You have a missing equals sign. When performing an if statement you must use 2 equals signs. Otherwise the value is assigned to the variable.

i.e.

(valu4=="no") means "If valu4 is equal to no"

(value4="no") means set valu4 to equal no.

[CODE]
<SCRIPT TYPE="text/javascript">
function Woo(){
var valu4 = ('no');
var valu1 = prompt('Hight in cm =','0');
var valu2 = prompt('Width in cm =','0');
var valu3 = prompt('Weight in grams =','0');
var valu4 = prompt('is it a parcel yes or no','?');

if ((valu1<32)&&(valu2<25)&&(valu3<100)){(price='30p');}
if ((valu1>31)||(valu2>24)&&(valu3<100)){(price='50p');}
if ((valu1<32)&&(valu2<25)&&(valu3<500)){(price='60p');}
if ((valu1>31)||(valu2>24)&&(valu3<500)){(price='80p');}
if ((valu3<1000)&&(valu3>499)){(price='&#1032;3.00');}
if ((valu4[COLOR=red][B]=[/B][/COLOR]='yes')&&(valu3<500)){(price='&#1032;1.65');}

if (valu3>999)
{price=3;
valu3-1000;
valu3/500;}

alert(price);}
</SCRIPT>
<body onload="Woo()";
</body>

@JMRKERJun 08.2007 — Either your formula is incorrect (remove the ';' after price=3; and put in correct operators between 3 segments)

or you have forgotten to make assignments (xx=valu3-100 and yy=valu3/500).

Sort of depends upon your intent.

@rootJun 08.2007 — I would also point out that their is a practical minimum size for a postage item, which I believe is A7 in size.

Items smaller than this will need to be packaged in a larger envelope or box. So your item could be a 2cm square box but the package could be an A5 jiffy bag for example and you would need to pay the postage price for sending an A5 package and not a 2cm square box...

So check because you could be losing out on your ACTUAL postage costs for postage...

Success!
