I built an interface for the ribbon where two variables ( a dropdown and a string field) provide the inputs por a query. However, most ribbon actions are 1 to 1 (only a single input before starting the action). 


<dropDown id="WU" label="Select choice: " sizeString="xx">
<item id="WU_1" label="FL" />
<item id="WU_2" label="GA" />
<item id="WU_3" label="TN" />	
</dropDown>
<editBox id="WU_CityName" sizeString="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" onChange="WU_CollectData" />
How can I collect both inputs for my code?

Thanks....
