I have never delt with arrays and trying to learn as i try and build a shopping cart app. Can someone please try and help me understand why i am getting this error message...
Microsoft VBScript runtime error '800a000d'
Type mismatch
/exhibitparts/config/inc_functions.asp, line 35
Below is the line on 35...
arrProdQty = Session("ProdQty")
Session("ProdQty") is holding an array which i check with the function IsArray.
What i am doing is storing the info into the array, saving it to a session object (which works) then taking the session object and putting it back into and variable to work with.
any help?

I think the problem is that even though IsArray tells you that session("ProdQty") is an array, when you do something like this
MyVar = session("prodqty") myVAr is a string
try this, don't know wether it would work
array(myVar) = session("prodqty").
You could also use the dictionary object if this is available on your server, it is useful for storing arrays.

Ok i got this problem fixed, now here is my problem...
I am saying my data to an array and retrieving that array on another page.
Here is the code i use to add it to the array...
arrCart(pCartIndex,0) = strProdID
pCartIndex is the number of Array it gets inserted it into. Example 1, 2, 3, 4, etc..
I retrieve the Array on the next page and loop thru the items by this code...
for f=0 to pCartIndex-1
strSessionProductID = session("myCart")(f,0)
Response.Write strSessionProductID & "<br>"
next
is their anything special about arrays? i have been reading and cant seem to locate whats wrong. if anyone can help ill show them the two files that use this code cause i really need it done.

You should copy the array out of the Session collection to a local variable before iterating through it.

Well I am not really getting an error. If you want to view the shopping cart goto
http://www.exhibitparts.com/exhibitparts/store/category.asp?cag_id=1
If you add one product, everything works fine. Add another one, it makes the first one go empty and adds the other one so it works. add another one, it deleted the 2nd, it erases the text and adds the correct data for the 3rd one. if you keep adding products i think you can understand but i only have 2 procuts in it so far.

Just a tip on Arrays
When stored in a Session object they can-not be modified. You must first retrieve them, then modify, then put back into Session if required. ie
Dim MyArray(x,x)
MyArray(0,0) = Value 1
MyArray(1,0) = Value 2
Session("StoredArray") = MyArray 'Saves the Array as Session Variable called "StoredArray"
MyArray = Session("StoredArray") ' to retrieve the Array
If you'd like to post some more code, or even email it to me, I'd be happy to take a look at it for you.
