multiplying variables 1

[leadman]

Im trying to multiply variables to get a total but its throwing an error. i need the two cart variables to be multiplied first and then added to 'cartweight'. The following works fine but doesnt include the quantity of each item (session.cart[4]):
<cfset cartweight = cartweight + #session.cart[5]#>

but this doesnt work:
<cfset cartweight = cartweight + #session.cart[5]# * #session.cart[4]>

neither does this:
<cfset cartweight = cartweight + (#session.cart[5]# * #session.cart[4])>

or this:
<cfset cartweight = cartweight + ((#session.cart[5]#) * (#session.cart[4])>

the error is this :
Just in time compilation error

Invalid parser construct found on line 7 at position 76. ColdFusion was looking at the following text:
> (or &quot&quot;, depending on which of the above i tried)
Invalid expression format. The usual cause is an error in the expression structure.

any ideas?

Hi! Don't you need another # after #session.cart[4])>
in the examples above?

In other words:
not this:
<cfset cartweight = cartweight + (#session.cart[5]# * #session.cart[4])>

use this:
<cfset cartweight = cartweight + (#session.cart[5]# * #session.cart[4]#)>

Actually you don't need the # signs at all in a cfset statement unless it is in quotes. I noticed on the second one that you are missing the end parenthesis.

Try:
<cfset cartweight = cartweight + ((session.cart[5]) * (session.cart[4]))>

If all else fails try:
<cfset cartweightNew = cartweight + (#session.cart[5]# * #session.cart[4]#)>
