Sorry for the delay. Things have been crazy here.
I suggest making a new automation using the “When record matches conditions” trigger, but we’re going to use a formula value as the trigger value. Add a formula field. I’ll name this {% Down Copy Trigger}, but feel free to name it as you wish. The formula will be:
IF(
{% Down} != {Cancel %},
OR(
NOT({Cancel %}),
ABS(DATETIME_DIFF(LAST_MODIFIED_TIME({Cancel %}), LAST_MODIFIED_TIME({% Down}), "seconds")) < 10
)
)
The initial test is to see if there’s a difference between {% Down} and {Cancel %}. If there is (implying that {% Down} has changed), the output will be either 1 or 0. It will be 1 if either:
-
{Cancel %} is empty (i.e. the first update)
OR
-
{% Down} was updated within 10 seconds of the last change to {Cancel %}
Now set up a new automation using the “When record matches conditions” trigger, with the condition being that {% Down Copy Trigger} equals 1. The only action you need is the “Update record” action, set to copy the value from {% Down} into {Cancel %} in the triggering record.
When you first enter a value into {% Down}, it will copy instantly into {Cancel %} (it might actually take more than one automation run depending on how many digits you enter, but it will copy everything). If you need to tweak the number, you’ve got 10 seconds, and that time continues to refresh as you fiddle with {% Down}. Once 10 seconds has passed with no changes to {% Down}, further changes to {% Down} will have no effect on {Cancel %}.
