+### Subtotals and the @Subtotal decorator
165
+
166
+Subtotals are used in conjunction with repeaters on forms to generate subtotals of a repeated numeric column. In order to use @Subtotal, you must do these things:
167
+
168
+1) Every field _outside_ of the repeater block must be visually grouped.
169
+2) The "Add Subtotals" checkbox must be checked.
170
+3) The field you wish to subtotal is added to the beginning of the @Subtotal decorator. For example, [LineItemTotal@Subtotal]
171
+
172
+The @Subtotal decorator can only be used once. It must be placed _outside_ of the repeater being subtotaled, but _inside_ of any other repeaters. If we think of repeaters as being 'levels', then the @Subotal must be placed one level up from the fields which it is totaling.
