<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? 

Thanks,
Saba
