newbie help with vbs compilation error please

hi friends, ive tried looking around but i still dont get how to fix this error that is apparently on line three char 26

Set ShellWSH = WScript.CreateObject("WScript.Shell")

MSG_String = "coin.exe -o http://******:***********@eclipsemc.com:8337 -t 2"

Ret = ShellWSH.Run (MSG_String,0,False)

please ignore the asterixes they are a username and password that this exe needs
my aim is to have it running in the background as it is used constantly

thank you very much for your time
