+\paragraph{Input Values of a State}
+At Section /state/inputvalues it is possible to add Definitions for InputValues.
+Those values have two meanings for the State.
+
+\begin{itemize}
+     \item They were used to fill the SQL-Statements to fetch the Data
+           (Each entry replace one ore more "?" )
+     \item They were used to validate the Inputdata which is "feed" to
+           the FIS in the current State
+\end{itemize}
+
+WARNING: The Order of the InputValues is significant at which position the Value will
+be put into the SQL-Statement.
+
+It is possible to add one InputValue twice or more often to put its value at
+different positions of the SQl-Statement.
+
+\begin{lstlisting}
+<inputvalues>
+    <inputvalue name="featureid" type="Integer" multiselect="false" usedinquery="1"/>
+    <inputvalue name="fisname" type="String" multiselect="false" usedinquery="0"/>
+    <inputvalue name="parameterid" type="Integer" multiselect="true" usedinquery="0"/>
+</inputvalues>
+\end{lstlisting}
+
+\begin{itemize}
+    \item name: Name of the Value that could be feed or should be used in SQl-statment.
+                The name must fit to one dataname configured in this State or one other
+                State which was visited before.
+    \item type: The type of the Value. This is required for the Validation 
+                of the Value.
+                This might be String, Integer, Double, Date, Point, LineString, 
+                Polygon, Coordinate, Geometry and AttributeName.
+    \item multiselect: true if more than on Value can be feed or put into the SQl-statement.
+                       false if one on Value will be accepted.
+    \item usedinquery: Number how often the value should be put into the SQL-Statement:
+                       0: Value will not out into the Statement.
+                       1: Value will put once into the Staement,
+                       2 or more: Value will be put as often as configured 
+                                  into the SQL-Statement (this is useful if 
+                                  Inner-Selects are used)
+\end{itemize}
+
+The next part will explain the usage of inputvalues.
+
+This SQL-statment is configured to use in the State above.

+\begin{itemize}
+    \item featureid: 4 (Marnet)
+    \item fisname: fis\_marnet
+    \item parameterid: not set because it's the value that should be

+The value of featureid will be inserted into the Query because

+
+
+If the Attribute usedinquery of the inputvalue featureid is set to "2"
+this might happen.
