Hi @Giorgio67
What data source are you using? If it's SharePoint, the StartsWith function should be delegable.

Also, is your intention here to definitely use the logical And operator, rather than the Or operator?
Filter(dblist;StartsWith(text1;txt1.Text) ||
StartsWith(text2;txt1.Text) ||
StartsWith(value.Value;drop_text.Selected.Value))
