URGENT: Java Developer Needed To Fix Application

I am having trouble with a simple java application. The application is used to automatically fill a web form out. It pulls the data from an excel sheet and then inputs it onto the webpage. The problem is the data is defined incorrectly in the app, so for certain fields. For example, the Zip Code field is defined as a string when it should be Int...the result is it fills out the forum with a zip code with a decimal at the end. A few of the fields have these issues and they just have to be redefined. Looking to get this done within the hour, let me know if you have any questions.
