Using a ListBox to enter data into specific cells help please!!!!!

I have coursework to do and I have hit a brick wall. I need a code that inputs data into certain cells when a selection is made from a ListBox.
For example, In the ListBox I will have name of events, such as

Girls swimming competition

Boys swimming competition

When I select Girls swimming competition I want the data I typed in the Textboxes to go into the cells which are part of the Girl swimming competition table on the sheet. Then when I select Boys swimming competition I want the data I typed in the Textboxes to go into the cells which are part of the boys swimming competition table on the sheet.
