You really only need to do something like
I know, but I wanted a list of variables in a block and an empty block
yeah, but having another block to report an empty string is useless and takes up a lot more space in the project file.
You can also do this
and just saying, when resetting a variable, it usually means setting it to 0, not nothing.
it won’t work, all the variables will take as value their names
but the for i = () to () block doesn't fill in empty slots. I also checked that this works.
