I'm having some trouble copying the html script onto ebay.
I go to my product page and right click "page source" Copy then paste in the html function of my ebay listing.
However ebay keeps giving me the error
Can any one help me remove this from my script?
Britton here with the Shopify support team.
It sounds like your eBay listing doesn't allow for scripts. Generally on the product pages those will be identified as code blocks starting with "<script>" and ending with "</script>". If you remove all bits of code like that you may have more luck.
That being said though, copying the page source of a Shopify product page over to another service is probably not going to work very well. There are a lot of things in that page source that are specific to Shopify and likely will not port over well to eBay in the way you mentioned. It would probably make more sense to contract a developer to helo you desing your eBay listing if you wanted to go that route.
I hope that helps!
