First of all, it's, "What's wrong with this sentence?"
I can't find any grammatical mistakes here in the second sentence, unless 'did' should become 'does'.
Hope this helps, ~Taco

The sentence is grammatically correct, but the verb 'did' suggests a past action. Depending on what you want to convey, you might consider changing the tense to present or adding more detail. Overall, it’s well-structured but can be improved for clarity.
