我想在网址中添加一个随机数，结果没有输出，求大神看看我这样写有什么问题
[MeasureCalc]
Measure=Calc
Formula=(Random)
LowBound=260
HighBound=260
UpdateRandom=1
[MeasureRSSTitle]
Measure=Plugin
Plugin=Plugins\WebParser.dll
UpdateRate=1800
Url=http://www.zzsky.cn/code/mrmy/mrmy/#MeasureCalc#.asp
RegExp="(?siU)<div id='hwmrmy'>(.*)</div>"
CodePage=936
StringIndex=1
FinishAction=!Redraw
[MeasureRSS]
Measure=Plugin
Plugin=Plugins\WebParser.dll
Url=[MeasureRSSTitle]
StringIndex=1
[MeterLink0]
Meter=String
MeasureName=MeasureRSS
MeterStyle=styleRightText
W=1000
H=500
FontSize=15
FontColor=222,255,227,255
AntiAlias=1
DynamicVariables=1

LowBound=260
HighBound=260
上限与下限一样的还随什么机呢
