Hi,  
Could I get a little bit of information on functions containing Event and also Event=Event?  
Here’s an example of each.

[color=#FF00FF]def[/color] refreshTablesb[/b]:  
root = fpmi.gui.getParentWindowb[/b].rootContainer  
source = app.util.getRootb[/b].getComponent([color=#8000FF]“Dest Table”[/color])  
dest = app.util.getRootb[/b].getComponent([color=#8000FF]“Source Table”[/color])  
sourceEquipmentID = source.EquipmentID  
destEquipmentID = dest.EquipmentID

[color=#FF00FF]def[/color] refreshDataSetsb[/b]:  
app.woq.updateSourceTableb[/b]  
app.woq.updateDestTableb[/b]

Functions usually do not have scope within the event handler that triggered them (when defined within that event). So you have to pass the event variable as a parameter to the function. [See more on Python functions](http://www.tutorialspoint.com/python/python_functions.htm).
