Macro help - guild invites

Hello,

I am receiving the below error when I attempt to run a script in chat. I do not think it's working as a macro button either.

The code is as follows:

-----------------------------------------------------------------------------------------------------------------------------------
/script n=GetNum!@#$%sults(); i=1; while(i<n+1) do c,g=GetWhoInfo(i); if(g=="") then SendChatMessage("Hello "...c..."! <Syndicate Alpha> is now recruiting PvP players!, Join now!","WHISPER","COMMON",c); GuildInvite(c); end; i=i+1; end;
-----------------------------------------------------------------------------------------------------------------------------------

Any assistance greatly appreciated
TIA

GetNum!@#$%sults is not the name of a function... The real name is GetNumWhoResults but it gets censored because of the s****horpe problem

/script n=GetNumWhoResults(); i=1; while(i<n+1) do c,g=GetWhoInfo(i); if(g=="") then SendChatMessage("Hello "...c..."! <Syndicate Alpha> is now recruiting PvP players!, Join now!","WHISPER","COMMON",c); GuildInvite(c); end; i=i+1; end;
