Dear Sir,
Sorry for the confusion.
Currently the update property for "Target Completion (Estimation)" stated as Datepicker2. This means whenever i input a new date and submit, a new date will be entered in sharepoint column.
Now, if i toggle button to false, i disable the datepicker2, and would like to update sharepoint column with "TBC"
Quite unsure whether i correctly explained.
Mean user could choose either "TBC" or select a date by select the toggle to true or false. If Toggle selected to false, then date not more applicable and not entered in sharepoint list but will ident as TBC.
Thanks
