No part 'Left' in package com.google.appinventor.components.common.HorizontalAlignment

Hi everyone.
can someone please tell me what this error means.

no part ‘Left’ in package com.google.appinventor.components.common.HorizontalAlignment.

if i can just know what it means i can figure out where to search.
i’m using a dynamicComponents extension to make a list. The items on the list i get from a dictionary.
if you want to see my block please ask.

Thanks.

We shouldn’t need to. Showing your blocks is necessary 99% of the time as no one on here is a mind reader or has a crystal ball.

Do you set Horizontal Alignment using the word Left ? If yes you should use numbers

  • Left is 1
  • Center is 3
  • Right is 2
