SCENARIO: a calculation field with 20 repeats, all repetitions showing horizontally in a portal row, and the field designated as a button.

QUESTION: is it possible to click on a specific repetition of the field and have the repetitiion # identified and passed on? (i.e. click on rep #5 of 20 and pass the rep# to a specific field for use in other calculations.)

Because the field is designated as a button, it cannot be entered - hence the 'Get ( ActiveRepetitionNumber )' function cannot be used.

Anyone have any ideas, or is this impossible?

It's posible to put exactly the same calculation in 20 releated records shown in a portal, that adresses the values in the record where the portal is shown, since the realtion now is bidirectional, as well as a portal can be cut into pieces and arranged horizontal.

If however you're set on repeating fields, could you make 20 invisible buttons sized to fit a single repetition ...to grasp the corresponding value in the repeating field underneath use GetRepeating( as a parameter for the shared script.

Take a look at the template!
