Error running ./lotrosetup-0.1.5.sh

["mirdragon" <wineforum-user@xxxxxxxxxx>]

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
