The first parameter to SelectDirectory is a var parameter,
so you need a variable in the call.
The error message is a bit unfortunate.

I dont understand how to make it work.
Is it flawed by design or is it just a simple error? This app is ment to be
a demo but it seems to be full of glitches and i really have no desire to
reright the application.

It wants a variable, so you have to call it like this:

var wheretolook:string;
begin
wheretolook:='where to look';
selectdirectory(wheretolook,'',dir) then (etc)
end;

That usage of SelectDirectory is fine for the VCL version of that
function. There are some other renditions of that function that are only
valid in the CLX version. Since I only have Delphi 5, I cannot help you
sort out the difference between VCL and CLX. I do know that you'll need
to get rid of any units from the uses clause that start with Q, such as
QDialogs.
