Please help, I can't complete swap/transaction

Seeking advise !!

Would like to swap but unable to click the confirmation button, even the slippage tolerance is increased to 11. , it’s saying not enough gas fees. Normally they cut the fees from existing coins, right? I have enough to coin to swap or do I need to transfer additional BNB coins just in order pay the gas fees. I am really frustrated, please help.

Your help would be highly appreciated.

Many thanks.
