I need to filter an array using previous simple numerical field. Is it possible? Any idea?

Example:
Q1: How many products have you bought? (Numerical)
Answer: 2

Q2: Rate each product... (Array)
Product 1: Bad - Good - NA (show)
Product 2: Bad - Good - NA (show)
Product 3: Bad - Good - NA (hide)
Product 4: Bad - Good - NA (hide)
...
