Any tips on where I’m going wrong?

My initial prompt produced the photo I was keen on “a beautiful white couple standing at a high table in a dimly lit bar, talking close to each other smiling there are people mingling in the background f/2.8 editorial photography he is wearing an expensive grey suit with navy blue shirt she is wearing a dark green velvet gown wide angle he has warm brown wavy hair he has green eyes he is clean shaven she has a brown bob and a straight fringe she has blue eyes she is holding a vodka and cranberry drink --s 800 --style raw --v 6.0 --no beard”

I had created a prefer option set without —cref in the value field (I’ve also created with —cref in the value field and it didn’t work then either! Although it seems to work seamlessly in the YT videos I’ve watched!) of a few different photos of the characters I want to in paint in to this photo.

I then launch vary region and highlight first over the females face area, with the following prompt, removing any sections of the prompt that don’t refer to her, “a beautiful white couple standing at a high table in a dimly lit bar, talking close to each other smiling f/2.8 editorial photography she is wearing a dark green velvet gown wide angle she has a brown bob and a straight fringe she has blue eyes —cref https://cdn.midjourney.com/2a1fb882-1d02-4bc4-88bd-101192f3fd4f/0_0.png --s 800 --style raw --v 6.0 —cw 0” I’ve also tried the “—cref —jade” in place of the actual image URL (my prefer set option) and in both cases, I received the error: “Submission Error!: SyntaxError: The string did not match the expected pattern”
Any tips of how to get the cref function to work in vary region so i can get multiple of my characters to appear in the image??
