Hi I added a new unit (unit2), made there a procedure and tried to use it in unit1, to do so I added in unit one: uses unit2;
and unit2:
uses unit1;
Then I added in unit one in the interface the header of the procedure, but then Delphi always shows a mistake.
Any suggestions?

The proper way to do it would be:

unit Unit1;

interface


implementation

uses Unit2;

...
{use proc Proc2 from unit Unit2}
Proc2;
...

end.

unit Unit2;

interface

procedure Proc2;

implementation

procedure Proc2;
begin
  {do whatever here}
end;

end.

You do not have to specify "uses Unit1" in Unit2 unless you need Unit1 for some purpose in Unit2. If so, then take care that only one of the units is referring the other one in the interface part (the other one has to reffer the first in the implementation part to avoid a loop).

If you knew all this, please forgive me for the detail and post some more detail on your particular problem.

HTH,
