Dont seem to have any luck with this one. No matter what portal row I click in, this function always reads 0. How do I get it to display the portal row number for the row within which field I am in?

This function, along with several others, does not refresh very satisfactorily when used in a calculating field.

Originally, all the status functions were designed for use in scripts. To varying degree, they can be adapted for use in other ways (such as in calculations) but Status(CurrentPortalRow) is one of those that are not so flexible.

If you use a script to set the current portal row into a field you will probably have more success.

If you want to pursue this approach, you may wish to consider turning the "Allow entry into field" setting off for your portal fields, and defining them as buttons to trigger a script which sets ip the current portal row value in a number field (for display on your layout) and then takes you into the field you've clicked on.
