修改kession.label.commoncls.asp中的GetTags函数  

Function MyRnd(NumMin,NumMax)
        Randomize
        MyRnd = Int(Rnd * (NumMax - NumMin + 1)) + NumMin
  End Function

'TagChannel可以指定ChannelID，生成对应栏目的热门标签，为空时，生成所有栏目热门标签

'isRnd指定样式，1：字体不一;2:颜色不一;3：字体和颜色都不一;其它：默认方式

  Function GetTags(TagType,Num,TagChannel,isRnd)
    if not isnumeric(num) then exit function
    dim sqlstr,sql,i,n,str,srnd,col(6)
    col(0)="BLACK"
    col(1)="RED"
    col(2)="BLUE"
    col(3)="GREEN"
    select case cint(tagtype)
     case 1:
     if TagChannel="" then
      sqlstr="select top 500 keytext,channelid,hits from ks_keywords order by hits desc"
     else
      sqlstr="select top 500 keytext,channelid,hits from ks_keywords where channelid="&TagChannel&" order by hits desc"
     end if
     case 2:
     if TagChannel="" then
     sqlstr="select top 500 keytext,channelid,hits from ks_keywords order by lastusetime desc,id desc"
     else

     end if
     if n>=cint(num) then exit for
    next
   
  End Function

请问版主这个代码应该怎么用呢？
