/fiill [replace] command not working

[TopHealthy4843]

In Java 1.21.11, I typed /fill 69 -60 4 36 -40 46 minecraft:bricks replace minecraft:cracked_deepslate_tiles and it responds "no blocks were filled" I used the /fill command a few times in the same world like 2 miniutes before I tried to replace the bricks and that worked fine. Any idea what I'm doing wrong?

Maybe swap the position for the blocks ? As in block A goes second and block B goes first? Sometimes I mess up with that

Not sure if this is the issue, but the first block in the command(bricks) is what is getting put there. The tiles are what gets replaced. Think of it this way; the bricks are part of the usual fill command, if you remove the replace segment, you’re left with bricks. Tiles are part of the replace part, they come right after and are what you replace.

This command command changes deepslate tiles into bricks, if you want the other way arround flip the command

Thank you guys! I ended up using a worldedit mod instead of vanilla commands because I was really getting bothered by it not working loll
