Hi@bogdankorda,
Please provide the specific error message and your column type which is the key to this problem.
And, please check my solution again to define which scenario you are in.
If the column you fill the Dropdown is a Choice type,
In my scenario, I set the Items of the Dropdown as below:
Choices(DataSource.ColumnName)
Set the Default property of the TextInput as below:
Dropdown1.Selected.Value​
If the column you fill the Dropdown is a Text type,
In my scenario, I set the Items of the Dropdown as below:
Distinct(DataSource,ColumnName)
please set the Default property of the TextInput as below:
Dropdown1.Selected.Result​
Note that if you set the Dropdown as DataSource.ColumnName directly, you should change Default property as below:
Dropdown1.Selected.ColumnName
Hope it helps.
Regards,
Qi
