A developer needs to use the COUNTIF function to process data entered by the user...

In OmniScripts, if you need to apply a function (like COUNTIF) to dynamic data and show the result immediately, the Formula element is the correct choice.

B. Formula element – The Formula element supports real-time calculation using OmniStudio expression functions (like COUNTIF, SUM, etc.) and updates values instantly on the screen without the need for server calls.

Incorrect Options:

A. Set Values element is used to set static or conditional values but doesn’t support formula evaluation.

C. Range element is used for value comparisons and conditions, not for calculations.
