Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

I am trying to make 5 boxes, one in the center and one in each quadrant of the screen and my script keeps getting stuck here. I checked for matching brackets and parentheses and that I'm not missing any multiplication symbols but I still get the below error every time. Any advice?

    locations=[(center(1)-offsetx-(.5*boxsize),center(y)-offsety-(.5*boxsize),center(1)-offsetx+(.5*boxsize), center(y)-offsety+(.5*boxsize));...
        center(1)+offsetx-(.5*boxsize), center(y)-offsety-(.5*boxsize),center(1)+offsetx+(.5*boxsize), center(y)-offsety+(.5*boxsize);...

Try this.

locations=[center(1)-offsetx-(.5*boxsize), center(y)-offsety-(.5*boxsize),center(1)-offsetx+(.5*boxsize), center(y)-offsety+(.5*boxsize);...
           center(1)+offsetx-(.5*boxsize), center(y)-offsety-(.5*boxsize),center(1)+offsetx+(.5*boxsize), center(y)-offsety+(.5*boxsize);...
           center(1)-offsetx-(.5*boxsize), center(y)+offsety-(.5*boxsize),center(1)-offsetx+(.5*boxsize), center(y)+offsety+(.5*boxsize);...
           center(1)+offsetx-(.5*boxsize), center(y)+offsety-(.5*boxsize),center(1)+offsetx+(.5*boxsize), center(y)+offsety+(.5*boxsize)];
