错误类型：

Syntax error

<%  dim nt,ms
          nt = request.QueryString("nt_upid")
          if nt = "93" then
           ms="Images/1_r5_c3.png"
          else if
           nt = "94"
           ms="Images/PRODUCTS-2.2-SFP_r3_c2.jpg"
          end if  %>
        <td colspan="2"><img src="<% ms %>" width="190" height="30" />

改成这样试试。。

还是错误 我改用CASE语句 提示
�������ͣ�
Microsoft VBScript runtime (0x800A000D)
Type mismatch
/product.asp, 第 32 行
32行是<td colspan="2"><img src="<% ms %>" width="190" height="30" />



<%  dim nt,ms
          nt = request.QueryString("nt_upid")
          select case nt
          case nt = "93"
          ms="Images/1_r5_c3.png"
          case nt = "94"
          ms="Images/PRODUCTS-2.2-SFP_r3_c2.jpg"
          end select  %>
        <td colspan="2"><img src="<% ms %>" width="190" height="30" /></td>

把<img src="<% ms %>"改成<img src="<% echo ms %>" 程序没报错 但是MS没有值

<%=ms%>

还是没有值··

<% Response.Write(ms)%>没有值  而<% Response.Write(nt)%>输出了94
WHY?？？

问题已解决 case nt = "93"
改为case 93

nt=93是一个很正确的布尔表达式，返回的是布尔值，自然没法跟你的条件表达式对应上了。

写代码格式很重要，不要这样写了，最后连自己都不认识
        <%  dim nt,ms
          nt = request.QueryString("nt_upid")
          if nt = "93" then
          ms="Images/1_r5_c3.png"
          elseif nt = "94" then
          ms="Images/PRODUCTS-2.2-SFP_r3_c2.jpg"
          end if  
           %>
        <td colspan="2"><img src="<%=ms%>" width="190" height="30" />
