Loop increment and decrement

General

Hi All,

I create node to loop an auto increment then decrement. But my code didn't works. Here is my code:

[{"id":"f0e1fc36.bea","type":"debug","z":"d67945fe.28ff9","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":1089,"y":1024,"wires":[]},{"id":"828e0993.766d1","type":"function","z":"d67945fe.28ff9","name":"","func":"var max = 100;\nvar min = 1;\nvar x = msg.payload;\nvar step = 1;\n\nsetInterval(function() {\n  console.log(x);\n  x += step;\n  if (x === max || x === min) {\n    step = -step;\n  }\n}, 150);\nmsg.payload = x;\nreturn msg;","outputs":1,"noerr":0,"x":806.5,"y":1058,"wires":[["f0e1fc36.bea"]]},{"id":"234a16e.ee0f8ea","type":"inject","z":"d67945fe.28ff9","name":"","topic":"","payload":"1","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":606.5,"y":1064,"wires":[["828e0993.766d1"]]}]

Thank you for any advice

What are you wanting to happen?

You inject something (anything) and it starts counting 1 to 100 then 100 to 1?
Repeating....

Looking at the code, I think it is way above my skill set.

Sorry.

Hope some one else can help. I don't think I can.

So, what do you see in your console? You can change the console.log() to a node.warn() and see it in the debug. I'd also suggest changing the loop from 150 to 15 for testing.'

When you see what you get, ask yourself 'Why is this happening?" and think about what you are seeing and why you see what you see.

Yes, I want to start counting from 1 to 100 then 100 to 1.
