How to assign string to integer? [duplicate]

Question

Here is the code now:

procedure TForm1.Button1Click(Sender: TObject);
var j,r:integer; k:string;
begin
  k := Edit1.Text;

  if StrToInt(k) > 0 then 
    if StrToInt(k)<10 then
      r := StrToInt(k);
  if StrToInt(k) = 10 then
    r := 1;
  if StrToInt(k) > 10 then 
    if StrToInt(k) < 190 then
      j:=StrToInt(k) mod 10;
  r := j-1;

  ShowMessage('Na toj poziciji se nalazi: '+ IntToStr(r));
end;

When I write k:=Edit1.Text option is not even suggested to use. Anybody got a solution?

Welcome to SO! To assign text from TEdit instance to your Integer variable, you can use StrToInt function and specify Edit.Text` as its argument. — Josef Švejk

Yes I know. But here on SO we ask one question at a time. Once you have an answer, the question is over. It's fine to edit the question to improve or clarify the original question, but not to ask new questions. I believe this is covered by the topics at the help center. — David Heffernan

FWIW, calling StrToInt(k) everywhere is not really a good idea. The conversion from string to integer takes time and doing it again and again will slow down your program (ok, not this trivial code, but it could become important in a larger project). Rather do myInt := StrToInt(k); once and then use that integer instead. — Rudy Velthuis

you are trying to set 'k', which is declared an integer, to a string from Edit1.Text

Convert Edit1.Text to an integer using StrToInt and try it again. BTW the message: "Incompatabile types: 'Integer' and 'TCaption'" means exactly that. It's incompatible.
