Why can't i buy anything on Binance?

Hello there, I'm having some trouble with Binance. I'm wondering why I can't seem to purchase anything on the platform. I've checked my account balance and everything seems to be in order, but every time I try to make a purchase, I get an error message. Could it be something to do with my verification status? Or is there a specific reason why I'm unable to buy anything on Binance? I'd really appreciate it if you could help me out with this issue. Thank you.
