Issue with emit redstone precedure

I am creating a block that is supposed to emit redstone with power 15, when given a redstone signal. This is so that one base block that gets powered will trigger all the others (stacked vertically) to emit redstone. But after many failed attempts bouncing between procedures for the triggers, "redstone on," "redstone off," and the "emitted redstone signal: ", I either had minecraft crash, or (for the later variant,) the block not function right. Does anyone have an idea for how I can make this block work with the redstone the way I want?
