Fetching data from Text Databank variable from a different test

This is my use case:

Test 1: Extension Tool
Add output --> Text Data Bank
(Extract 2 data variables StartDate and EndDate)
Test 2: Do SOAP calls
Add output --> XML DataBank
Test 3: Extension Tool Parameterize Call
Add output --> Text Data Bank
Test 4: QueryDBUsingvalues
Add output --> Text Databank

My problem:

The two dates that I'm storing in Databank (start and end dates,) I'm unable to use them from Test 3 because I dont get any value returned: Here is my code for Test 3:

from com.parasoft.api import *
from java.util import *
from soaptest.api import *
from java.time import LocalDate
from java.time import LocalDateTime
from java.sql import Timestamp

def fetchOrders(input, context) :
#theDateFilter=context.getValue("BetweenTimeStamp") ## from a previous extension tool

#Application.showMessage("The theDateFilter is: " + context.getValue("Generated Data Source", "BetweenTimeStamp") )    
Application.showMessage("The theDateFilter is: " + str(context.getValue("Generated Data Source", "Test 1: startDateTime") ) )
return 

The output in the console is --

---------- Test 3: Extension Tool ParameterizeSOACall ----------
The theDateFilter is: None
The theTrkSqlQuery is: 0

The allRowsCount is: 5848
The counter is: 5847

Test 3: Extension Tool ParameterizeSOACall - success
get trkSqlQuery=0
set allRowsOfData=select ATTRIBUTE1 from LOG_header lh where LOG_PROCESS_ID in ('681') and CURRENT_STATUS in ('STARTING', 'COMPLETED') and ATTRIBUTE1 not in ('

Test succeeded

Attribute values are set as show above but I cannot access them in Test 3.
What am I doing wrong?

I reviewed several forum posts on using variables, databanks etc., none of them led me to any resolution.

Any assistance is greatly appreciated. Thank you!
