Code: on :text:!mcuser:#:{ var %user = $readini(whitelist.ini, n, users, $nick) if (%user!=$null){ msg $chan MC username for $nick is currently set as %user $+ . else msg $chan $nick has no MC username set. } } When the script is triggered via "!mcuser" an error appears, saying Quote: /if: insufficient parameters (line 3, mcUser) with mcUser being the name of the script. As far as I'm aware, the syntax is correct. Can anyone see what's wrong? EDIT: I'm still unsure as to what is wrong with the above text, but amending the text to this: Code: on :text:!mcuser:#:{ var %user = $readini(whitelist.ini, n, users, $nick) $iif(%user=!$null, msg $chan MC username for $nick is currently set as %user $+ ., msg $chan $nick has no MC username set.) } solved it.
