HI @panda_2021,
A tip for you, tell us your column settings from beginning😂
Here is what I am confused, the screenshot you provided proves that the control corresponding to job title is a Text Input, which expects text value.
All the solution is based on a Text column for Job Title, this is the key to this issue.
So, now the issue is you have a multi select people picker, and you want to display job titles of each user in the Text Input control, right?
If so, please set the Default property of the Text Input control as below:
Concat(ForAll(ComboBox7.SelectedItems,First(Office365Users.SearchUser({searchTerm:DisplayName})).JobTitle),Value,",")
Note that ComboBox7 represents the Combo Box in your scenario used to select users.
