CHAT I NEED HELP

okok, so...

ive been trying to code on the profile

AND ITS SO CONFUSING

i was trying to add 2 cats in a blank space, ya know? and I got it to look good for a second... but only for a second

because i somehow lost the 2nd cat???

it turned into a white square and i could NOT change it :(

i dont even get how it got to that, all i did was move it a bit

then it fucking died ig
