+    <b>In Internet Explorer 5.0, 5.5 or 6.0, I cannot modify a row in a 
+    table with many fields.</b>
+    <br />
+    Your table does not have a primary key, so we must use a long URL to 
+    identify this row. There is a limit on the lenght of the URL in those
+    browsers, and this not happen in Netscape, for example. The workaround
+    is to create a primary key, or use another browser.<br />
