Let's add a frame
Initially, an added frame, or imported from Adobe Indesign, will have absolute coordinates, width & height.
Let's make these coordinates variable
The X-position (left side of the frame): -6 px. Why -6? The document has a "bleed" of 6px. This would be usefull if you will also use this document for print output. If you don't intend to output to print, you can set the bleed to 0, and the x-position will be 0px.
The Y-position (distance from the top of the document reference): -6px, similar reason as X-position.
