When I am in the first page that looks like an electronic Excel sheet, I click on one sample/row, and then enter the page that has the sample details, telephone number, comments and dispositions. How do I get back to the original "Excel sheet" style page without having to the page disposition (i.e. there should be a back button to back to the Excel sheet page but there isn't), the only way to go back is to set an appointment or disposition something, when sometimes I do not need to do that, I just want to look at it. I just simply want to go back. How can I do that?
