# forEach do multiple commands

I have a code in my rule like this:

`gShutter.members.forEach[ i | i.sendCommand("DOWN")]`

I need to replace it with one, that sends command DOWN and then waits for 1 sec before sending another command DOWN for the other member. I tried this:

`gShutter.members.forEach[ i | i.sendCommand("DOWN") && Thread::sleep(1000)]`

But this results in:

`org.eclipse.smarthome.model.script.engine.ScriptExecutionException: Unknown variable or command '&&'; line 161, column 38, length 44`
