I just checked, its not like that in the original code. <param name="input" type="select" size="300" label="Input Snapshot" area="True" help="Choosing Input Snapshot files" selected="false"> <options from_file="coyote.loc"> <column name="name" index="6"/> <column name="value" index="6"/> <filter type="param_value" ref="inputmodel" column="2"/> <filter type="param_value" ref="inputSize" column="3"/> <filter type="param_value" ref="inputRealization" column="4"/> </options> </param> On Feb 21, 2014, at 1:50 PM, Vipin TS <vipin.ts@gmail.com<mailto:vipin.ts@gmail.com>> wrote: <filter type="param_value" ref="inputmodel" column="2”/> <filter type="param_value" ref="inputSize" column=“3"/> If you closely look at the above line the double quotes are different for column field. <filter type="param_value" ref="inputRealization" column="4"/> </options> </param> Did you figure out where the problem is?
