Setup, Configuration and Use Scripts & Rules

I want to create a button that returns an ON value when confirmed and an OFF value when released.

How and with what can I create a rule in OH3?

I have created the following Rule:

Rule "Comannd Off after Time"
  
when
  item Rolloheben_ValueasSwitch received command ON
then
   createTimer(now.plusMillis(300), [
  triggeringItem.sendCommand(OFF)
  
])

but the log says this:

2021-05-03 12:37:23.389 [ERROR] [internal.handler.ScriptActionHandler] - Script execution of rule with UID 'a5a0950b80' failed:  ___ Rule  ___ "Comannd Off after Time"
  
when

then
   createTimer(now.plusMillis(300), [
  triggeringItem.sendCommand(OFF)
  
])
