Debug existing website/database/bot written in node.js

I have some existing files for my website+ database+ steam bot. I have a steam bot running node.js which sends trades, controls timer, gets prices for items from API. Right now looking for some bug fixes and bootstrap pop-up implementation for item deposits confirmation, so that it let's them confirm deposits before bot accepts trade+ possible revamp of design (currently using bootstrap).

Known bugs:

-Timer resets itself rarely when sometimes people join pot (In database starttime remains initial value (the value starting in 2) photo of the table with this: [url removed, login to view]

-Some prices display undefined/$NaN value when parsefloat(body) is used.

-Roulette is not working properly (roll is not stopping and notification is flickering)

[url removed, login to view]

If project is done fast I can extend contract for more features to be implemented.

Would also like to add to tab title a value from database which updates everytime.
