James has 18 chocolate bars in total.
He sold 5 last week and 7 this week, so he sold a total of 5 + 7 = 12 chocolate bars.
To find out how many more chocolate bars he needs to sell, we subtract the number of chocolate bars he sold from the total number of chocolate bars.
18 - 12 = 6
James still needs to sell 6 more chocolate bars.
#### 6
The answer is: 6
