I wanted to make an item the when used, it would grant the character a skill, provided he has achieved the
appropriate level for learning that skill. But I got stumped and I don't know what to do. I went to the
conditional branch of things but I can't figure out how to make it work. And somehow I consumed the item
but it doesn't grant the desired skill. Please help me.

Your screen is rather strange as it the normal version of VX, it displays "Constant" instead of "#". Anyways, this is used to check if a variable as is equal, lesser than or greater than a finite number. If you want to use it to check the level or the character, you need to set this variable to the character level first (with the "Control Variables" command).

Thanks for the quick reply. This is what I've been doing to the Common events page.
It'd be a great help to me if someone would help me. please point out if there something
wrong with my script as I'm a complete noob. Thanks in advance.

So like, basically, I want to have an item to grant a character a certain skill on a certain level (and consumed in the process).
And when that character did not meet the required level, the item is not consumed. I just need a point in the right direction.
Thanks in advance.

Please avoid posting twice in a row (I've merged your posts).

As for your event, it's almost good. You just need to stick everything out of the first conditional branch (which is useless).
Also, there is a bug in the default scripts which kicks in when you try to assign an actor level to variables. Read this post for explanations on how to fix it.

Thanks for the quick reply and sorry for the double post. I'll go over it. I'm gonna post again if I encounter
some problems in the future. Thanks again!
