I'm trying to optimise some code but am stuck.

This is my `trigger` node.

```auto
[{"id":"21982222.97dd2e","type":"trigger","z":"fb549e2f.4d026","g":"9f73c6fa33db761f","name":"","op1":"{\"command\": \"remove-all\"}","op2":"{\"command\":\"add\",\"name\":\"30\",\"payload\":\"30\",\"expression\":\"0 */30 * * * * *\"}","op1type":"json","op2type":"json","duration":"250","extend":false,"units":"ms","reset":"","bytopic":"all","outputs":1,"x":1330,"y":1800,"wires":[["15e1c4e1.b0dbab"]]}]

```

This part in particular:  
`{"command":"add","name":"30","payload":"30","expression":"0 */30 * * * * *"}`

The `30` part is variable.

It could be `5`, `10`, `12`, `15`, `20`, `30`, or `60`.

So the _event_ is done at those frequencies.

How can I make this value set by `msg.payload`, either in that node or I could construct the message in a `function` node and have that sent into the `trigger` node.

How about this? I don't now exacly what you want to do 😉  
Looks like adding stuff to the the cron-plus node?

Nice, but not quite.

The _second_ command needs to be a bit more.... _complicated_.

Your gives me nearly enough, but not quite enough.

Sorry I didn't mention it originally, but the message is being sent into the `cron-plus` node.

I need to add a schedule that repeats every.... 5, 6, 10, 12, 15.... etc minutes.

So it needs to be  
`{"command":"add","name":"30","payload":"30","expression":"0 */30 * * * * *"}`  
where the `30` is the message received and the entire line is what is sent.

Thanks.

Ooops.

Sorry.

I think that does work.

Adding multiple schedules to the cron-plus node at the given intervalls:

# GREATEST APOLOGIES

It did work.

Only 1 schedule needs to be active.

That's why I send the _WIPE_ command first.

I goofed when putting your code in my test flow and hadn't realised a mistake with it and the problem is my end.

It does work.

Thanks.

(That is the first one you posted.)
