You were close:

Code:

getCostumeFromX1: t1 y1: t2 x2: t3 y2: t4 
    costume _ ImageMedia new form: (Form fromDisplay: (t1 @ t2 corner: t3 @ t4)).
    costume mediaName: (self unusedMediaNameFromBaseName: 'costume').
    media addLast: costume.
    self costumeChanged.
    self updateMediaCategory

Aww! Dang we were too close!

AHEM you did the following wrong:
1. the | t1 t2 t3 t4 | is already defined.
2. It should be below the getCostumeFrom... opening.

It's a syntax error! I didn't define the variables in my code, I copied MathWizz's code directly> once the block is run, a window with that code appears. There the variables are declared and set!

Are you missing the 'self'?

EDIT
If you did that logically, you're missing the self.
If not, declare the selector in the first line and put the var declarations after!

Add a dot after the self getCostumeFrom etc... i put a red bold blob where but i don't know if you can see it.

no, the line self getCostumeFromX1: t1 y1: t2 x2: t3 y2: t4. shouldn't be included, I think.

Adding it gives an error saying message not understood: self getCostumeFromX1: t1 y1: t2 x2: t3 y2: t4.

because it was supposed to be a block definition, smart one.

It goes on the top, and then you put everything under.

You put that at the TOP!

You should have said if you wanted a block or a command.
