+=== The sum of all values in a field... ===
+
+The case:
+Your resource contains a "timestmp" field (type datetime) and a field "cost" (type double), and now the user shall select a time interval in aform, and your report function shall provide the sum of all "cost" for those records with a timestmp within the selected time interval.
+
+Let's go:
+
+First of all, we implement our method handler as before:
+
+{{{
+def shn_xxx_yyy_report(r, **attr):
+
+    # Report generating code goes here
+
+s3xrc.model.set_method("xxx", "yyy", method="report", action=shn_xxx_yyy_report)
+}}}
+
+Now we add the HTML representation:
+
+{{{
+def shn_xxx_yyy_report(r, **attr):
+
+    if r.representation == "html":
+        output = dict()
+        return output
+
+s3xrc.model.set_method("xxx", "yyy", method="report", action=shn_xxx_yyy_report)
+}}}
