Creating an NFT Mint Page

I am running into errors integrating the NIFTYKIT coding into my website. I have followed all of the directions on this page but my mint page is still not functional. The wallet connect and mint looks fine but doesn't actually do anything. Has anyone else in web3 tried to create a mint page on their squarespace website? I would love to know how you did it. Did you use nifty kit or another platform? Looking to make this simple and smooth. Thanks!

Which of the two installation methods described in the link you sent are you using?
