wine users - Sep 2010 - Error running ./lotrosetup-0.1.5.sh

When I run the lotrosetup-0.1.5.sh script at Step 3: Specify Video Memory it
exits with the following message before i even type anything

./lotrosetup-0.1.5.sh: line 207: typeset: /1024: syntax error: operand expected
(error token is "/1024")

how do i get past this

using wine 1.2 on Linux Mint 9 64bit

thanks

think i've resolved this

had to remove the "/1024" out of the script
also had to change other parts of the script to get it to work

still other bits to fix to get the files already downloaded installed
