Automation "wait for a condition"

Hello
I have a “Processes” where I call a “Task” several times, but I need to give it time between calls, I think that about 10 seconds would serve between calls to make it work properly, but what I was concerned about was the following … …

TOTALSECONDS (TIME (TIMENOW ()) - TIME ([UPD]))> TOTALSECONDS (“00:00:15”)

but [UPD] that is in the table where the process says that it does not exist …

Could anyone help me ?
Thank you
I don’t know if it works anyway, any other ideas?
