Inserting Data - Maximum Characters Exceeded In Statement

I am new to SQL but have managed to create a table with five columns. The problem I am having is when I try and run the INSERT command I get an error "Maximum characters exceeded in SQL statement"

My table code is:

create table myemployees_MPA0510
(FirstName Varchar (15), LastName
varchar (20), Title varchar (25),
Age number (3), salary number (9));

And my INSERT code is:

Insert into myemployees_MPA0510
(First, Last, Title, Age, Salary)
Values ('Jonie', 'Weber', 'Secretary', 28, 19500.00) ('Potsy', 'Webber', 'Programmer', 32,
45300.00) ('Dirk', 'Smith', 'Programmer II', 45 75020.00) ('Mark', 'Aldridge' 'Technical', 52,
12000.00) ('Peter', 'Wright' 'Admin' 30, 11000.00) ('Lucy', 'May', 'Technical', 15500.00)
('Robert', 'Hurst', 'Finance', 54, 16000.00) ('Ann', 'Green', 'HR', 43, 21000.00);
