For example, suppose that the major dimension is rows and that *Max results*
is set to *25*. The poll returns no more than 25 rows of values.
++
+When *Range* specifies the major dimension and you also specify
+*Max results*, polling uses the lower number to determine how much
+data to return. Consequently, setting a value for *Max results* is
+more helpful when you specify only the minor dimension for *Range*.
+For example, consider a sheet that has 30 rows with three columns of
+values in each row. Suppose that *Major dimension* is *Rows* and
+*Range* is *A:C*. If you set *Max results* to *10*, polling returns
+10 rows of data. If you accept *0* as the setting of *Max results*,
+polling returns 30 rows. However, if you specify *Range* as *A1:C15*
+and you also specify *Max results* as *25*, polling returns 15
+rows. If you specify *Range* as *A1:C30* and you also
+specify *Max results* as *25*, polling returns 25 rows.
