Script Error Help TTT

Keep getting this error:

[ERROR] gamemodes/terrortown/gamemode/vgui/sb_team.lua:81: attempt to perform arithmetic on field 'Width' (a nil value)
1. unknown - gamemodes/terrortown/gamemode/vgui/sb_team.lua:81

There are no visual differences to the GUI related to this issue (that I am aware of)

I am currently using [URL="http://facepunch.hatt.co/showthread.php?t=1268194"]Mortuus's Scoreboard Rank System[/URL]

Any help?

My current sb_team.lua file is [URL="http://pastebin.com/6JTzPSjG"]here[/URL]
