window is almost an exact copy of the Specify Calculation window, except it has an extra
text box at the bottom labeled Result, and it has two new buttons: Evaluate Now and Monit-
or.
Figure 13-8. The Data Viewer's Watch tab shows what you want to watch. You load it up with vari-
ous calculation expressions, and it keeps tabs on their results for you. If you want to see a field
value, then just put the field all by itself in the expression. Variables work the same way. But unlike
the Current tab, you can even put variables and complex calculations here and watch them as
things change. In this window, the fourth line calculates the path to the file currently in use. Switch
to a different file, and the path will automatically update to show that file's path.
Differences aside, you can do anything here that you can do in the ordinary Specify Calcula-
tions window. In the Expression box, just enter any formula you want. When you click
Evaluate Now, FileMaker performs the calculation and shows the result in the Result box at
the bottom of the window. You can use this handy feature to test a calculation and correct it
without jumping in and out of the dialog box.
When you're satisfied with the formula, click Monitor. FileMaker adds the expression to the
Watch list, with its value beside it. FileMaker attempts to keep the values up-to-date, but it
can't auto-refresh some kinds of calculations (typically those that use Get functions). If ne-
cessary, you can click Refresh Values to automatically recalculate each Watch expression.
