 AllowOnly: This function allow entering just the specified

 Parameters:
      Expression = Allowed characters.
                   a..z => ONLY LETTERS
                   0..9 => ONLY NUMBERS
                   other symbols...

 Example: use the onKeyPress event to make this function work:
          //Allows only from A to Z
          onKeyPress="AllowOnly('a..z');"

          //Allows only from 0 to 9
          onKeyPress="AllowOnly('0..9');"

          //Allows only A,B,C,1,2 and 3
          onKeyPress="AllowOnly('abc123');"

          //Allows only A TO Z,@,#,$ and %
          onKeyPress="AllowOnly('a..z|@#$%');"

		  //Allows only A,B,C,0 TO 9,.,,,+ and -
          onKeyPress="AllowOnly('ABC|0..9|.,+-');"

 Remarks: Use the pipe "|" symbol to separate a..z from 0..9 and symbols
