please help me i am a programming newbie

[1337h4x0r]

i am doing a software design class for my first year i had a written this psuedocode for a Timer type program type program, my teacher tells me there are errors in it i dont know whats wrong could you tell me please.
here it is

Program Timer
Var
mm = integer, dd = integer
BEGIN
PROMPT USER
Leap year = true
               Case of MM:
                           4,6,9,11 :              LAST_DAY = 30
                           1,3,5,8,10,12:        LAST DAY = 31
                           2:       do checkLeapyear
                                      if THINGO = true
                                      LAST_DAY = 29
                                      Else
                                      LAST_DAY = 28
                                      End-if
                           Else: ERROR_FOUND = True
                 End-case
        If ERROR_FOUND = false
                     If dd <1
                             or DD > LAST_DAY
                             ERROR_FOUND = true
                     End-if
End-if
DISPLAY RESULTS

This is my sub program for leap year

SUB CHECKLEAPYEAR
Var
YYYY, quotient, remainder : interger
leap year                         : interger
BEGIN
    leap year = false
    quotient = yyyy/400
    remainder = yyy - (400*quotient)
    If remainder = > 0
            leap year = false
    else 
            quotient = yyyy / 100
            remainder = yyy-(100*quotient)
            If remainder = > 0
                   quotient = yyyy / 4
                   remainder = yyy - (4*quotient)
                   If remainder = 0
                           leap year = false
                   End-if
             End-if
  Endif
EndCHECKLEAPYEAR

any advice would be really really nice thanks ^____^

The following is C++ code (for the most part, I'm outta practice)
I searched on the 'net and found the following:
leap years occur in years exactly divisible by four,
except that years ending in 00 are leap years
only if they are divisible by 400.

void Calendar()
{
     int month, day, year, last_day; // declare variables
     cin >> month; // get month 1-12 from user mm
     cin >> day; // get day 1-31 from user dd
     cin >> year; // get 4 digit year from user yyyy
     switch (month)
          {
          case 4, 6, 9, 11 : last_day = 30; break;
          case 1, 3, 5, 8, 10, 12 : last_day = 31; break;
          case 2 :
               {
                    if ( checkLeapYear(year) ) last_day = 29;
                    else last_day = 28;
                    break;
               }
          default : Error();
          }
     if &#40; &#40;day > last_day&#41; || &#40;day < 1&#41; &#41; Error&#40;&#41;;
&#125;

bool checkLeapYear&#40;int year&#41;
&#123;
     bool leap_year = false;
     if &#40; &#40;year % 4&#41; == 0&#41; // modular &#40;remainder&#41; division
     &#123;
          leap_year = true;
          if &#40; &#40;year % 1000&#41;&#41; == 0&#41; // year is '00
               if !&#40; &#40;year % 400&#41; == 0&#41; leap_year = false;
     &#125;
     return leap_year;
&#125;

Check the links section (a link is on the top of every TTF page!). There is a very comprehensive C++ e-book for free at http://www.mindview.net. Also, there is a good Java book at that URL.
