Why has my checkout button stopped working after adding code?

[astrofinityligh]

I added some code but it just stopped working completely. I dont know what to do. I worked on this store for over two days and after im 99% done it basically just stopped now. Is there coding I can add to make it work? It worked THE WHOLE TIME I was doing it, and it just stopped.

I think it may have been coding I added but I dont know where to check. I added coding in a area other than the theme.scss section so maybe that is why and I may have not deleted it but i forgot where i added code to.... any idea of where i should check? please help.

Hello @astrofinityligh!
Hope you are doing well.

Please check this screenshot https://prnt.sc/QLgxsoSEpCRh, hope this will help you out in finding the code. Check in the theme.scss.css file for the .btn--primary

Hi,

I dont see the theme.scss.css file. Is that the same as theme.scss.liquid? Thx

Please check this one: https://prnt.sc/QLgxsoSEpCRh

Yes, please find the code in theme.scss.liquid file as you are not able to find the theme.scss.css file.
