The issue in your screenshot is very clear:

👉 Available Funds: 0.00 USDT

That’s why the “Buy NIGHT” button isn’t working — you simply don’t have any funds in your Spot wallet to place a trade.

✅ How to fix it:

1. Add USDT to your Spot Wallet

You have 3 options:

Transfer from Funding/P2P wallet

Go to Assets → Transfer

Move USDT to Spot wallet

Buy USDT via P2P

Go to P2P section

Buy USDT using bank transfer / Easypaisa / JazzCash (common in Pakistan)

Deposit crypto

Tap the “+” icon next to USDT

Deposit USDT from another wallet

2. After adding funds:

Return to NIGHT/USDT

Enter amount

Tap Buy NIGHT

⚠️ Important Note:

You also have this warning:

“This token has a Seed Tag and is likely to have higher volatility”

That means $NIGHT is risky, so only invest what you can afford to lose.

✔️ Summary:

Problem ❌: 0 USDT balance

Solution ✅: Add/transfer USDT to Spot wallet

Result 🚀: Buy button will work
