Place blocks in specific places to open a door?

But you also have to set the int in the block itself, so in your case you will need 5 blocks, one with the Block Number int set to 3, one set to 9, one set to 1, etc.

If you’ve already done that then I can’t see what could be wrong, if you want to upload the project somewhere and send a link on the forums PM I can check it.
