Dynamic Approval Group Scripting

[chrish5]

I need to have the approval group in my workflow be dynamic based on what the users selects from a request form field.   Here are the details.     My request form has a lookup select box called Location (location) that is referring a table holding all my locations.     I am using a BR to copy the selected location to a table column called Shuttle Location (shuttle_location).   I have a workflow associated with this request form with a group approval and this approval has to vary depending on the location is selected.   Each location has its own approval group.   And there are dozens of locations, thus the need to do this dynamically.   I could build this in the workflow with a switch flowing to all the different approvals, but that would be ugly and not very maintainable since locations will change.   I've tried using the below script to make this approval group dynamic, but I keep getting an error that "shuttle_location" is not defined.   Is this switch script the correct way to do this?   Should it be referencing the form variable location rather than the table column shuttle_location that I am copy location to?  

var answer = [];

switch(shuttle_location){

case 'nebraska city':

1. answer.push('Shuttle - Nebraska City');

break;

case 'new rockford':

1. answer.push('Shuttle - New Rockford');

break;

case 'jamestown':

1. answer.push('Shuttle - Jamestown');

break;

case 'amarillo':

1. answer.push('Shuttle - Amarillo');

break;

default:

1. answer.push('Default Approvers');

}

I inserted the updated script and ran a couple request thru.     When I search the message column for what is in variable, it is not finding anything.
