Is there a way to copy and paste code to a different page?

Hi there,

There's a 'grid' that I like on my homepage. I clicked it, edit as html, copied code. Then, I went to my services page and I tried pasting that code in a new grid's html editor. It doesn't work. I get a "This block contains unexpected or invalid content."

How can I make this work? Overall, I want to be able to duplicate containers that I made on one page for another page.

Thanks
