Not able to change Date Range in Pivot Table of Excel

[Limitless]

I have created a Pivot Chart, but I am unable to change the Data Range when I go to Select Data. (It's greyed out and unselectable.). The help tells me I should be able to do that, as follows. Furthermore it also seems to say that I only need to select the first cell when creating the chart, but that's not true. A message appears saying I need at least 2 rows of data!. From Help I found this :

1. On the Options tab, in the Data group, click Change Data Source, and then click Change Data Source. The Change PivotTable Data source dialog box is displayed.
2. Do one of the following. To use a different Microsoft Office Excel table or cell range, click Select a table or range, and then enter the first cell in the Table/Range text box.

You need to click on the Pivot Table, not the Pivot Chart, and then Options > Change Data source are available for you.

I see that is true now, and have finally understood the MS Help. One thing I have noticed with the Excel Help function is that once you figure a problem out yourself, (or through a group such as this) it finally makes sense.
