Final answer:
To make the sentence correct, change "none" to "any."
Step-by-step explanation:
To correct the sentence "I didn't think none of you wanted to go along," you can rewrite it as "I didn't think any of you wanted to go along." The double negative in the original sentence creates a grammatical error. By replacing "none" with "any," the sentence becomes grammatically correct.
