Question

asp购物车判断商品是否已在购物车里面，这段代码要加在哪里啊？

这是原来的代码：
<%dim k

session("spid")=session("spid")&request.QueryString("gid")&":"
session("num")=session("num")&"1"&":"

array1=split(Session("spid"),":")
array2=split(Session("num"),":")
k=0
%>

这是要判断的代码：
for i=0 to ubound(array1)-1
if array1(i)=request.QueryString("gid") then
ifbuy=true
exit for
end if
next

判断的代码要加在源代码的哪里啊？？请高手赐教
