Appsheet using bot to update existing row column

[Quan_W]

I am creating a Form view, for users to clock in and out. All the data will be stored in a Google sheet "Staff" sheet.

I am facing a challenge. When user time-out with the form, the bot that I set up doesn't update the value to the existing time-in row. Instead, it has become a new row.

---Current (Wrong)---

---Expect---

I have set up 2 action and 1 bot to write to existing row if there is a data change in "Staff" table. But it fail and below is the table, action and bot setting. May I know where went wrong?

---

This is my Staff Table setting: 

This is my Check Out Action: 

Referenced Rows:

 SELECT(
      STAFF[_ROWNUMBER],
      AND(
        [Name] = USEREMAIL(),
        [Date] = TODAY(),
        [Branch] = [_THISROW].[Branch],
        ISBLANK([Time Out])
      )
    )

This is my Set Check out time Action: 

Bot Setting 

Event Condition:

Not(ISBLANK(
  ANY(
    SELECT(
      Staff[Time In],
      AND(
        [Date] = TODAY(),
        [Branch] = [_THISROW].[Branch],
        [Name] = USEREMAIL()
      )
    )
  )
))

This is the error message from the bot "Test" result:

Failed: Error: 'Execute an Action on a Set of Rows' Data action 'Check Out' for

Found the solution. I have change the Data Change Type to "Add" and condition to something simpler ISBLANK([_THISROW].[Time In])
