You need another set of braces for the if statement
Code:
on *:text:*!give*:#:{
if ($nick isop $chan) && ($1 == %c $+ !give) {
.inc $+(%,$2) $3 
 msg $chan $2 was given $3 points, total is now $($+(%,$2),2) 
}
 }


or
Code:
 on *:text:*!give*:#:{
if ($nick isop $chan) {
if ($1 == %c $+ !give) {
.inc $+(%,$2) $3 
 msg $chan $2 was given $3 points, total is now $($+(%,$2),2) 
}
}
 }


Realistically the two codes above are the same.
