Single-value data can have only one value for the entire project, such as a project name or a project owner. In forms, single-value data is displayed in a single data field.
Therefore, to share single-value data in a form, switch to design mode and double-click a form control. Then, share the control with a single-value data field.
For example, you can share a single-value custom data field called Region with a control in the Task Progress Report.
Multiple-entry data can have multiple values for the entire project, such team members or x variables. In forms, multiple-entry data is displayed in data tables.
For example, you can share a multiple-entry custom data field called Risk with a new custom form you are creating.
