Hi @Poya Eghterafi , If I understand correctly, you have a linked question in your Lead Form that is linked to the project’s date and uses a date picker for selecting a date.
This field is not configurable for having blocked dates.
However, the scheduling tool is better suited for this task. I suggest setting a “session” for cake delivery in your Scheduler and having it set with availability. Then, provide a Lead Form with a scheduler for this “session,” allowing leads to see your availability before they book and allowing you to block the unwanted date and time options.
Also, if you go down that road, you have a session setting allowing you to use the meeting date as the project date, so you don’t lose functionality over your current flow.
Let me know if I can further assist you with the Scheduler or setting it in a Lead Form.
