Rootpage

[Tipmanfrank]

I have some problems to present my own text in Rootpage. Should be easy.

I have 3 strings made to one string. In the end text4 will contain a HTML page.

String text1 = "Dette er frank1 ";
String text2 = "Dette er frank2 ";
String text3 = "Dette er frank3 ";
String text4 = text1+text2+text3;

Now I have changed the rootpage function:

void rootPage(String test) {
  Server.send(200, "text/html", test);
}

And I call it from

void Setup{
    Server.on("/", rootPage(text4));
    if (Portal.begin()) {
      Serial.println("  WiFi connected: " + WiFi.localIP().toString());
    }
}

But I have Compilation error: invalid use of void expression.

How should I bring my own text into the rootpage?
