构造字符串的时候出错?
函数:
Function   SubBoard(bid)
if   bid   =   " "   or   isnull(bid)   then
Exit   Function
else
set   rs1   =   Server.CreateObject( "adodb.recordset ")
rs1.open   "select   *   from   suboard   where   bid   =   ' "   &   bid   & " '   order   by   paixu ",conn,1,1
if   not   rs1.eof   then
do   while   not   rs1.eof
SubBoard   =   SubBoard   &   " <tr   height= '30 '> <td   align= 'center '   valign= 'middle '   bgcolor= '#FFFFFF '> "

if   isNew(rs1( "subid "))   =   0   then  
  SubBoard   =   SubBoard   &   " <img   src= '../images/index_46.jpg '   width= '20 '   height= '19 '> "   //else
//SubBoard   =   SubBoard   &   " <img   src= '../images/index_43.jpg '   width= '20 '   height= '19 '> "
end   if  

SubBoard   =   SubBoard   &   " </td> <td   align= 'center '   valign= 'middle '   bgcolor= '#FFFFFF '> <a   href= 'main.asp?bid= "&rs1( "bid ")& "&subid= "&rs1( "subid ")& " '> <strong> "   &   rs1( "suboard ")   &   " </strong> </a> </td> "   &   Detail(rs1( "subid "))   &   " <td   align= 'center '   valign= 'middle '   bgcolor= '#FFFFFF '   colspan= '4 '> "   &   Articles(rs1( "subid "))   &   " </td> "
rs1.movenext
loop
else
exit   Function
end   if
end   if
End   Function

那开头的//,如果去掉,会提示出错:错误
Microsoft   VBScript   编译器错误   (0x800A0412)
必须是行中的第一个语句
/ichild_bbs/bbs/lib_test.asp,   line   173,   column   88
SubBoard   =   SubBoard   &   " <img   src= '../images/index_46.jpg '   width= '20 '   height= '19 '> "   else
---------------------------------------------------^

如果注释的话,就不会出错..

应该怎么修改呢?谢谢!


------解决方案--------------------
else不是在一行的?
