 strCatalog_name = Request.QueryString("strCatalog_NAME")
 
 ...
 
 ...
 
 strParam = Response.Write (rsCatalog("catalogID")) &strCatalog_NAME=Response.Write
 
 
 (Server.URLEncode(rsCatalog("catalogName"))) &rsCatalog("catalogName")
 
 
 --------------

"products where productID="&intProdID)
 
 if rsProdInfo.EOF then
 
Response.Write "Product Number " & intProdID & _
 
" does not exist."

C. Solution
 
 Using Replace String For Filter some character
 
- productsByCategory.asp
 
 
 * Find 
 
      intCatalogID = Request.QueryString("intCatalogID")
 
  After,add
 
      intCatalogID = Replace(intCatalogID,"'","")
 
 * Find
 
      strCatalog_name = Request.QueryString("strCatalog_NAME")
 
      After,add
 
      strCatalog_name = Replace(strCatalog_NAME,"<","")
 
 
- product.asp
 
 
 
 * Find
 
  intProdID = Request.QueryString("intProdID")
 
      After,add
 
      intProdID = Replace(intProdID,"'","")
