jQuery Forum

I have two check box to chose multiple choices.
1. If i select radio button, i want check box "By post" is checked.
2. If i uncheck check box "By post", i want radio button is unchecked.
3. When i check in radio Add4, i want to show the div "anotherStatementAddress". And when i check in others, i want to hide div "anotherStatementAddress".

The result:
1. The first time i select radio button, "By post" is checked. But when i unchecked this, i select radio button again, "By post" is not checked.
2. is ok.
3. The first time i select radio Add4. Div "anotherStatementAddress" show, but when i chose another radio button, it doesn't hide.

Anyone help me? Thanks.
