Solved If block at {_x} {_y} {_z} is {_block}

[Computerize]

  loop all players:
    set {_x} to x-coord of loop-player
    set {_y} to y-coord of loop-player
    set {_z} to z-coord of loop-player
    set {_totalUp} to 0
    if block at {_x} {_y} {_z} is "jungle wood bark block":
      loop 25 times:
        if block at {_x} {_y} {_z} is jungle wood bark block:
          add 1 to {_y}
          add 1 to {_totalUp}
        else:
          add 1 to {_y}
          add 1 to {_totalUp}
          if block at {_x} {_y} {_z} isn't jungle wood bark block:
            execute console command "/pex user %loop-player% add minecraft.command.tp"
            make loop-player execute command "/tp ~ ~%{_totalUp}% ~"
            execute console command "/pex user %loop-player% remove minecraft.command.tp"

The code above gives me the following error:
"Can't compare 'block at {_x} {_y} {_z}' with a text" - (Line 6)
Is there any alternative to do something like this?

you forgot to seperate the coordinates with a commma.

block at {_x}, {_y} and {_z}
