Right my question is What below is making the 'item_quantity' into a string?

is it the Trim function?



If Request("updateQ") <> "" Then
Dim cartU, newQ
cartU = Session("cart")
For i = 0 To Ubound(cartU, 2)
newQ = Trim(Request("q" & cartU(item_id, i)))
If newQ = "" or newQ = "0" Then
cartU(item_id, i) = ""
Else
If isNumeric(newQ) Then
cartU(item_quantity, i) = newQ
End If
End If
Next
Session("cart") = cartU
End If
%>




Before updating qauntity, I can get the Sum of the 'item_qauntity' column but after it acts like there not numbers anymore i.e 1+2= 12 :mad:
