I need help turning this code back to blocks

this link for some reason won’t let me convert all the code into blocks, even tho when I was updating the github page to this it was already in blocks does anyone know how to fix it?

Could be the size although normally it tells you if it’s too big.

seriously any makecode staff know how to fix this? I’m trying add loads of stuff for example a rare item which skips you near to the end of the level or straight puts you in the second level but I couldn’t turn it back into code blocks so any staff knows how to fix this?
