Help with SQL Challenge: Clothing alterations

I need help on step one:

CREATE TABLE clothes (
id INTEGER PRIMARY KEY AUTOINCREMENT,
type TEXT,
design TEXT
price TEXT);
ALTER TABLE clothes ADD price

INSERT INTO clothes (type, design)
VALUES ("dress", "pink polka dots");
INSERT INTO clothes (type, design)
VALUES ("pants", "rainbow tie-dye");
INSERT INTO clothes (type, design)
VALUES ("blazer", "black sequin");

It says that my one of my column names has a space in it, but I never had a problem with it before.

ALTER TABLE clothes ADD price INTEGER;
SELECT * FROM clothes;
UPDATE clothes SET price = "10" WHERE id = 1;
UPDATE clothes SET price = "20" WHERE id = 2;
UPDATE clothes SET price = "30" WHERE id = 3;
SELECT * FROM clothes;
INSERT INTO clothes (id,type,design,price) VALUES (4,"cardigan","stylish couture",40);
SELECT * FROM clothes;

I am trying to get data from the database and using the write query but when the images of the vlone hoodies load from the database, it loads blur but when I insert the image in the database it is okay. Please tell me why this is happening.
