Hi @elmps2018! Thank you for your response. I seem not be able to get the constraints work properly. The date is being stored as YYYY-MM-DD which is the format I am using in the constraint.
I have attached here the sheet I am using.
Also included is the async_assign_count function I am trying to use (following your response from another thread). I still seem not to be able to get it working. I hope you would not mind checking both for me. I have simplified the form and left just where the issues are which I have highlighted also in the template.
I would appreciate your assistance on where I am getting it wrong.date_Form.xlsx (64.4 KB)
