#DBLOAD id
%if (%numitems(%query((&name = @item.name), All))=0, #NEW all @item, #echo @item.name already in ID DB)
#DBSAVE id
#t- Identify

What's wrong with it?
Returns this error:
Error compiling script:

Maybe try changing the %if function to an #if command

You can also put #CALL in front of the %if function (or any other function for that matter) to call it and discard the return value.

But in that case, it wouldn't do anything, including running those commands.

Thank you man, it works perfectly now. Two quests, why use #if instead of %if ? Is there any major difference?, then why you put All in "", does it really need to be liked that?

Try it this way:

%if is a function, #if is a command. Generally speaking, commands do things and functions return things. There're some functions that do things as well as return things, but they're comparatively rare. Functions and variables can't be the only thing on a line in CMUD, because you haven't told CMUD what to do with whatever %if returns. You need a command to tell it what to do.

#say %if(@number>10,hello,goodbye)

The %if will return "hello", not send it to the MUD, when the number is above 10. It'd be as if you typed "#say hello" on the command line. Whereas the command:

#if (@number>10) {hello} {goodbye}

will send the command "hello" to the MUD if the number is more than 10.

#say %if(@number>10,hello,goodbye)
#if (@number>10) {#say hello} {#say goodbye}

do the same thing.

EDIT: Also, Anaristos' script has a number of syntax errors. You can't begin the line with %if, it needs to be #if, and you don't need the commas after the expression's closing ) and the command's closing }.
