browserDetect function problem

This is something that won't affect many sites however i thought i may share it.
I spotted recently that a bot under the name of StackRambler/2.0 (MSIE incompatible) is visiting my site.
HTTP_USER_AGENT  info of that particular browser causes the following error

Type mismatch: 'CInt'

in the

/functions_common.asp

lines

'MSIE 6 or below

        If  CInt(Trim(Mid(strUserAgent, CInt(inStr(1, strUserAgent, "MSIE", 1)+5), 1))) <= 6 Then
            browserDetect = "MSIE6-"
        Else
            browserDetect = "MSIE"
        End If

I updated the functions_common.asp today (with the newest version) and saw that this is still causing problems (i disabled this check in my former file)

Error: Type mismatch: 'CLng'
browser: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.25

code: If CLng(Trim(Mid(strUserAgent, CInt(inStr(1, strUserAgent, "Opera/", 1)+6), 1))) => 9 Then

hope it helps
