Hello. I'm new to Houdini. I recently started watching the Lake Houses tutorial, I'm near the end of the first video and I ran into an error which I can't understand why occurs.

I copy the “Seed” Parameter and then go to the “Size” Parameter of the box and I “paste relative references”.
And I get the error “Unable to evaluate expression (Syntax error (/obj/box1/SEED/stackboxes_seed)).
This is exactly what gets pasted: ch(”/obj/box1/SEED/stackboxes_seed")

Please help me, I need to continue with the rest of the videos
Not sure if I provided enough info for my problem, if I didn't let me know.

Thanks
