    Hi @Anonymous ,

    The default value of your dropdowm has to be the same format as the value property:

    Your formula: LookUp('myviewtable', 'ID '= ThisItem.'ID Entidade Vendedora') returns a record, but if you put 

    LookUp('myviewtable', 'ID '= ThisItem.'ID Entidade Vendedora').column ToShow you'll get the desired result.

     

    Hope it helps !

    Not from the error now, but the dropdown does not work, is blank and no more results appear.

    I was having a similar issue. I wanted the users to be able to edit their dropdown values after submitting/saving. At first the dropdowns were empty in edit forms. I solved this by adding a default value to the dropdown.
    In the default of the dropdown:
    ThisItem.'Field name that has the dropdown choices'. Value

    Also ensure the datacard default is:
    ThisItem.'Field name that has the dropdown choices'
    and the update value of the datacard is:

    dropdown.Selected
