Add a Find Records step that looks for records from Table 1 where the created time is today and the created by is “Anonymous” (since all forms are reported that way). If you don’t already have a “created by” and “Created time” field in Table 1, add them so you can do this.
If you also need to check for something similar in Table 2, repeat that^ with another Find Records step.
Move your Run a Script action to the “Conditional Actions” portion of the automation. Set the condition to be “If length of Found Records is at least 1”
