You currently have the textbox “Member ID” selected. Dates cannot be shown in a textbox, they have their own widget called the “datepicker”. If you click somewhere inside the “Member” data view without clicking on a textbox, you will be able to select the “birth” attribute and add it to your page by selecting it from the “connector” pane.
Alternatively you can manually add a widget and select the date picker. You can then also select the birth attribute in the datepicker's settings.
Thank you Eline, It´s working!
