Create dynamic Serial number column in portal

[salim]

I have a portal showing items, i want to have a column that displays serial number for each item, serial number has to start from 1,2,3,etc. i want the serial number to adjust accordingly when the user deletes any item, i.e. if user deletes item no. 3 i want all the items to shift up and fill the space left by number 3. How do i achieve this.? Am using filemaker pro 13.

You could simply type {{RecordNumber}} into the first portal row where you want to see that number:
