yes the problem is in my dialogproc

Code:

proc DialogProc, hwnddlg, msg, wparam, lparam
begin
        push    ebx esi edi
        mov     eax, [msg]
        cmp     eax,WM_COMMAND
        je      wmcommand
        cmp     eax,WM_DESTROY
        je      wmdestroy
        xor     eax,eax
        jmp     finish
    

it says ERROR! the argument 'hwnddlg' MUST begins with dot then when i add dots to the arguments it says if .__info.frame undefined symbol at begin
