Hello guys, I'm new to mIRC scripts, and did a "hi" script for the channels I'm in, the thing is, I want to make a user cooldown for my script, but don't know how, I tried to find something that fit my script but was unable do find it.

Here is the script:
Code
ON *:TEXT:*:#: {
  if (($1 = oi) || ($1 = oie) || ($1 = oii) || ($1 = oiie) || ($1 = oiii) || ($1 = ola) || ($1 = olá)) {
    msg # $nick Oi marsbmpHi  
  }
}


Can anyone help with this? Thanks
