’Variable not defined’ for banner

Hi,

I'm trying to add a random banner to the forum, but I'm getting an error.

The script (from haneng.com) works fine on it's own, but when I include it in the forum (V6.28, in the footer) I get an error.

If it is included in the footer as another include, I get:
"Microsoft VBScript runtime error '800a01f4'

Variable is undefined: 'LowestNumber'

/forum/banner.asp, line 3"

If I add it to the footer itself, I get the same thing (different line number, but same line of code).

The initial part of the script is:
<%
RANDOMIZE
LowestNumber = 1
HighestNumber = 6
RandomNumber = INT((HighestNumber-LowestNumber+1)*Rnd+LowestNumber)
SELECT CASE RandomNumber
CASE "1"%>

I'm sure it's something simple (I'm not a programmer), could anyone point me in the right direction?

Thanks in advance,

Thanks Blair, that worked perfectly

Dunno why it worked on its own, but not within other pages? I guess because of all the other variables going on.

Do I need to 'destroy' those varaibles afterwards?

Thanks,
