Else Statements

I am listing for someone that has the ability to be able to take information on a certain page in Javascript or if possible in php and transfer it to the child window. This is a simple task so please do not make it complex this is the only requirement. Also that the child window is able to send the information back to the parent window then update to the child window in a specific html section. The budget for this is $50 .We already have the money in our account so we can escrow immediately as soon as an hour. Pm me for more details.
