Hello @Nacked ,
The issue you're facing with the `Concat` function not recognizing "Obszar" likely stems from PowerApps not recognizing it as a field within the items selected from ComboBox5. This can happen if "Obszar" is not the correct field name within the items or if there's a syntax error.
To address this, make sure that "Obszar" is indeed the field name that contains the value you want to use from the `SelectedItems` property of `ComboBox5`. If "Obszar" is correct, then the formula should look like this:
Dzielnica: Concat(ComboBox5.SelectedItems, Obszar & ", ")
However, if "Obszar" is not recognized, it might be because it is not directly accessible, perhaps due to it being a complex object. In such cases, you should use the `Value` property or another relevant property to access the text within "Obszar". The formula would be:
Dzielnica: Concat(ComboBox5.SelectedItems, YourSubField & ", ")
Replace `YourSubField` with the actual subfield name that holds the text value in your collection. If "Obszar" is a column in a table, you might need to use `YourCollectionName.Obszar`.
Also, ensure you are using the correct syntax for your environment. The semicolon `;` is typically used in some locales instead of a comma `,` to separate arguments in a function.
If these solutions do not work, it might be helpful to revisit the structure of the data source and collection to ensure the fields are correctly named and accessible for the `Concat` function.
Best regards.
