Currently, the built-in functionality of the dynamic text box only works for single-select Combo Boxes. There is a workaround for this but you have to use R CODE for example: Calculate the number of selections in the Combo Box numberofselections <- length( Combo.box .4) Store what has been selected in the Combo Box selectiontext = Combo.box .4 if/else to print the correct text if (numberofselections == 1) { paste0("Verbatim reasons for recommendation rating - ",text\[1]) } else if (numberofselections == 2) { paste0("Verbatim reasons for recommendation rating - ",text\[1]," , and ",text\[2]) } else if (numberofselections == 3) { paste0("Verbatim reasons for recommendation rating - ",text\[1]," , ",text\[2]," , and ",text\[3]) } In this example, the customer had possible categories the user could select in a Combo Box. With the current functionality this only works for single select. When you change the Combo Box to multi-select there is an error.
