Winsock Example Frage

[CoYoTE]

Hallo
versuche anhand des Internets Google mit Tutorials Delphi zu lernen.
Nun das ist das erstemal das ich mich überhaupt an ein Forum wende Sonst habe ich immer alles geschafft mit Google.
Google hat mir Z.b. php beigebracht.
Ich komme nun leider überhaupt nicht weiter weis nicht was falsch ist an dem Code schnipsel.
der Client funktioniert eben dieser Teil hier nicht.
Wäre echt geil wen sich das mal ein Profi anguggt und mir sagt was daran falsch ist und mir erklärt wie ich das Problem behebe. Brauche Hilfe ich probiere seit 3 Tagen dran rum lol ich gebe erstmal nicht auf mal sehen woran es liegt.
hier der Code:

Delphi-Quellcode:

program prjServer;

  Windows,
  SysUtils;
