WHAT DID I DO?
I too started over at one time and 2nd time around I got a magnifying glass to assist in viewing the Figures. You must give the exact page number, chapter and section that will assist in determininga possible resolution. My page 4 talks about Oracle.and it is not an exercise page.
Am I to understand you have resolved your earlier problems and now you are on page 115 #4 and #5? If so, I made a note on that page to myself that states "page will state "no entries found" at this point, MUST Continue in order to see the results in Figure 4-25."
If that is not where you are the never mind and wait to hear from you.
Hope this helps.
