So you need something completly else. After your `select_multiple` question you need to crate a `repeat_group` with [repeat\_count](https://xlsform.org/en/#fixed-repeat-counts) = [count-selected(${name\_of\_your\_first\_question})](https://docs.getodk.org/form-operators-functions/#count-selected)  
inside that group you can add the question you want to be repeated and it will be repeated accordingle to the number of selected items in question one.

> Hello, New Question, Same form, is there a way that I can make a choice of say 3 out of 10 things, and then the nested repeat loop happens only for those 3 things. e.g. I have to collect information by team in different classrooms, some classrooms will have 3 teams, some will have 10 . Is there a way that before the repeat starts, the teacher chooses Teams (which are standard named as Team 1, Team 2 .....) and then the repeat function happens only for that chosen list ?

> Dear all, Can anyone send me an example (xls) with a repeat with multiple selection. I want to create a form with a list of multiple herbicides and do some repeating questions for each herbicide that is selected. There was some discussion topic on this, but I can't get this thing work in my excel. Most of the discussion there is on the Xform-level, for which I don't have enough experience... Would be good to have an example form... Many thanks in advance! Kind regards, Ed
