Fehler in der Projektdatei (Anfänger)

[BUG]

Delphi-Quellcode:

uses
  Forms,
  Unit1 in 'Unit1.pas' {Form1},
  Unit2 in 'Unit2.pas' {Form2},
  Unit3 in 'Unit3.pas' {Form3},
  Unit4 in 'Unit4.pas' {Form4},
  Unit5 in 'Unit5.pas' {Form5},
  Unit6 in 'Unit6.pas' {Form6},
  Unit7 in 'Unit7.pas' {Form7},
  Unit8 in 'Unit8.pas' {Form8},
  Unit9 in 'Unit9.pas' {Form9},
  Unit10 in 'Unit10.pas' {Form10},
  Unit11 in 'Unit11.pas' {Form11},
  Unit12 in 'Unit12.pas' {Form12},
  Unit13 in 'Unit13.pas' {Form13}; // <== Semikolon!

An deiner Stelle würde ich auch mal über sinnvolle Bezeichner für die Formulare nachdenken.
