So I am trying to use the money feature but it just wont seem to work I have both plugins. What Line do I change and with what word I cant seem to find it 

Set this in your config file to true :

"Use Economics to buy boat": true​

Thank you will try now 

Sorry to get back to you late but it still seems not to work might it be someother conflicting plugins 

Not really possible to be a conflict; the plugin is calling Economics to handle things, it's not something that can conflict.

Ok so here is what it looks like from my side 
{
"Can buy RHIB": true,
"Can buy rowing boat": true,
"Cooldown time in seconds to use the chat command to spawn a boat": 60,
"Cost of RHIB": 2000,
"Cost of rowing boat": 400,
"Interval in minutes to check boat for wipe": 5,
"Shortname of item needed to buy boat": scrap,
"Time before boat wipe in minutes": 15,
"Use Economics to buy boat": true,
"Use ServerRewards to buy boat": false
}

I also made sure I gave myself the money 

Do you see any messages at all when you attempt to buy it?

You can't buy a rowing boat.

That message would show if "Can buy rowing boat": false, so wouldn't be related to Economics.

Are you sure you reloaded the plugin and the setting is set to true?
