Filter not working

[TS5]

Hi Guys,

i'm quite a newbie to Power Apps, therefore im making some dumb mistakes.

It would be awesome, if you could guide me the way to success. In this particular case, I've got a problem with filters, the Datasource is a Share Point list.

Somehow it does not work...

there is the same mistake... 😕 execution of a unknowen or undefined function

May be it is because of the ',' instead of ';'.

Could you please try the below code ? 

if(!IsBlank(TextInput1.Text);Search(
   if( !IsBlank(ComboBox1.SelectedItems.Value);Filter(
        Fehlerprotokoll;
        Status in ComboBox1.SelectedItems.Value
    );Fehlerprotokoll);
    TextInput1.Text;
    "RTV_x002d_Nummer"
); if( !IsBlank(ComboBox1.SelectedItems.Value);Filter(
        Fehlerprotokoll;
        Status in ComboBox1.SelectedItems.Value
    );Fehlerprotokoll))
