Take another look at the sentence:

Because Jonathon had forgotten to bring his wallet to school, he buyed a bag of corn chips instead of the Salisbury steak with mashed potatoes, the lunch special that caught his eye.

The second verb, buyed, is incorrect. The sentence requires the simple past of buy, an irregular verb; the correct form is bought. Buyed is a spelling error.

buy buys(s) bought bought

Had forgotten, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
