Hello guys, I’m having some troubles with dynamo codeblocks coding, maybe some of you see something. I’m learning this new technology.

Error: “,” expected

The error should be pretty straight forward. There’s an expected “,” missing somewhere, likely for a list. The easiest thing to do would be to split up your code until you can determine where.
