That worked like a charm. Also quick question if your free. Do you know how to show a person column in a dropbox/combo box, without nesting it inside a form control?
When I set my sharepoint list as a source, the person column doesn't appear as an option. Do I need to do a specific type of filter to show all the entries inside that column?
EDIT
After doing some testing I found that I can get the person column working using Choices
My code now looks like this for the combo box which will hold the selected items from the other combo box's:
Filter(
Choices([@ITRequestForm].On_x0020_Behalf_x0020_Of),
"Not sure what should go here" in Concatenate(
ComboBox3.SelectedItems.DisplayName,
", ",
ComboBox3_1.SelectedItems.DisplayName,
", ",
ComboBox3_2.SelectedItems.DisplayName
))
