Code:

[Form:Save Aggregate Data]
Parts:Save Aggregate Data
Width:30% Page
Height:30% Page
Horizontal Align:Centre
Vertical Align:Centre
on:Form Accept:Yes:Form Accept
On:Form Accept:Yes:Call:Log Values

[Function:Log Values]
000:Log:#SADBody[1].SADName

[Part:Save Aggregate Data]
Line:SAD Title, SAD Body
Repeat:SAD Body
Scroll:Vertical
Break On:$$IsEmpty:#SADName

[Line:SAD Title]
Use:SAD Body
Local:Field:Default:Type:String
Local:Field:Default:Delete:Modifies
Local:Field:SAD Serial No:Set as:"Serial No"
Local:Field:SAD Name:Set as:"Name"
Local:Field:SAD Age:Set as:"Age"

[Line:SAD Body]
Fields:SAD Serial No, SAD Name, SAD Age

[Field:SAD Serial No]
