Process SOAP response and use those values as variables

Hello,

I have a SOAP Request that I am trying to get the out parameters as variables but every time I run the workflow it is successful but I am not able to assign the out variables as parameters (but if I assign the parameter and do a system.log it works but it doesn't work if I want to use the result as a variable for another part of the workflow)

Here is the Output:

[2015-04-30 14:31:30.437] [I] processing response...

[2015-04-30 14:31:30.437] [I] out headers...

[2015-04-30 14:31:30.468] [I] out parameters...

[2015-04-30 14:31:30.475] [I] out parameters available:

[2015-04-30 14:31:30.478] [I]   + parameter attribute name: '.(xmlns)', value: 'http://SystemCenter.JPMChase.net/'

Here is my scriptable task:

var getRequestStatusResult = outParameters.get("GetRequestStatusResult");

var content = getRequestStatusResult; // the XML text value of GetRequestStatusResult parameter above ( '<Response> ...  </Response>' ) 

var doc = new XML(content); // parse the whole response

serviceRequestNumber = doc.OutputParameters.ServiceRequestID;

Service_RequestStatus = doc.OutputParameters.ServiceRequestStatus;

serviceRequestCreated = doc.OutputParameters.ServiceRequestCreated;

serviceRequestCompleted = doc.OutputParameters.ServiceRequestCompleted;

currentActivity = doc.OutputParameters.CurrentActivity;

currentActivityTitle = doc.OutputParameters.CurrentActivityTitle;

activityStartUTC = doc.OutputParameters.ActivityStartUTC;

activityEndUTC = doc.OutputParameters.ActivityEndUTC;

durationTotalSeconds = doc.OutputParameters.DurationTotalSeconds;

averageDurationSeconds = doc.OutputParameters.AverageDurationSeconds;

secondsOffAverage = doc.OutputParameters.SecondsOffAverage;

estimatedCompletionUTC = doc.OutputParameters.EstimatedCompletionUTC;
