New field not appearing in mobile app

@RohitRattan88 Thanks for the advice but the code you have suggested doesn’t work. I explained that when I remove my abv line then other 2 fields still appear, using the syntax Item#PurchaseUnit and Item#SalesUnit, so I think the syntax is correct.

The screen doesn’t have a container called ‘Item’ so I cannot add to that. It has 2 containers, ‘HeaderView’ and ‘ItemInventorySummary’. The full mobile code is below. My Abv line in written in the same style of the existing lines.

add screen IN202520 {
  openAs = Form
  add container "HeaderView" {
    add layout "HeaderLayout" {
      displayName = "HeaderLayout"
      layout = "HeaderSticky"
      add field "InventoryID"
    }
    add layout "FooterLayout" {
      displayName = "FooterLayout"
      layout = "FooterSticky"
      add layout "Line1" {
        displayName = "Line1"
        layout = "Inline"
        add recordActionLink "ReviewAvailability"
        add recordActionLink "ScanBarcode"
      }
      add group "ChangeModeGroup" {
        displayName = "Change Mode"
        collapsable = True
        collapsed = True
        add layout "Line3" {
          displayName = "Line3"
          layout = "Inline"
          add recordActionLink "ScanModePick"
          add recordActionLink "ScanModePack"
          add recordActionLink "ScanModeShip"
        }
        add layout "Line4" {
          displayName = "Line4"
          layout = "Inline"
          add recordActionLink "ScanModeReceive"
          add recordActionLink "ScanModePutAway"

Hi @RohitRattan88, I’ve reviewed the post, but this isn’t the same problem I’m trying to resolve. I have been able to add a field to a screen, the sales and purchase unit field are working fine. The Abv field causes the problem.
