+If you have field names that are substrings of other field names (e.g., \usertext{col1}
+and \usertext{col10}) you should
+indicate so, by surrounding the field name (and the \% character) with square
+brackets (e.g., \usertext{[\%col10]}). This will prevent the \usertext{\%col10} field
+name being mistaken for the \usertext{\%col1} field name with a \usertext{0}
+on the end. The brackets will be removed by QGIS when it substitutes in the
+value of the field. If you want the substituted field to be surrounded by square
+brackets, use a second set like this: \usertext{[[\%col10]]}.
