"There were some problems with what you posted…"
@license and @description are meta keys. They are (mostly) required. Find a tutorial about writing user scripts if you don't know what meta keys are. Then if you're still having problems, comment with what you're trying to post.
First, it tells me:
"There were some problems with what you posted…
You did not specify a @license."
It doesn't tell you how to specify one. There is a link to a page of licenses to select from which you then copy to cliboard and I assume paste into your description. I did that, but it doesn't work. So I just checked the box "Save without a license" and now it just says:
"There were some problems with what you posted…
Description is invalid"
It doesn't tell me what's invalid about it. What am I supposed to do?
