Sending email alerts based on responses in a form for a schedule

Sending email alerts based on responses in a form for a schedule

Hi
I have 4 fields named below with data type in brackets:
1 Feedback_required? (Yes/No)
2 Date_Feedback_To_Be_received (Date)
3 Feedback_Received? (Yes/No)
4 Feedback_Received_date (Date)

I would like this to happen under Schedule possibly done through script:
If Feedback_required is Yes and Date_Feedback_To_Be_Received is known, then I would want a alert or email notification to be sent every weekday until Feedback_Received is Yes and a date is entered in Feedback_Received_date. 

Cheers
Casper
