where is the problem?

package advancedConditionalStatements;

Hi,

The brackets in your code are completely messed up, do you use proper Java IDE for writing code?

To check if value is equal you use double '='. I don't know the purpose of this:

if isValid=false;{, but it's wrong and any IDE will mark it as invalid.

After fixing the code, so it compiles, you have 2 mistakes.

1. System.out.printf("%2.f", commission); - the correct format for 2 decimal places is %.2f

2. The value for commision percent is wrong in the case with town=Varna and sales amount between 500 and 1000. It is 0,75(75%), but it should be 0,075(7.5%)

I suggest you to start using Java IDE and post the code in pastebin in future questions. Also to post link to the task in judge
