number
Originated in 
FileMaker Pro 6.0 or earlier
Description 
When no portal row contains the focus, this function returns 0. If there are multiple windows open in the current database file, each window can have its own portal row number value, but results are returned for only the foreground window. If a user navigates to a portal without selecting a specific portal row and without making an object active within a specific portal row, Get(ActivePortalRowNumber) returns row 0 rather than row 1.
Note  For information on how functions evaluate differently on the host versus the client, search the FileMaker Knowledge Base available at www.filemaker.com/kb.
Examples 
Returns 5 when the fifth row of a portal has the focus, or when the focus is in a field in the fifth portal row.
