this creates two test tables and three nested procedures, with transactions:
if exists (select * from sysobjects where id = object_id(N'[dbo].ProcedureA') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].ProcedureA
if exists (select * from sysobjects where id = object_id(N'[dbo].ProcedureB') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].ProcedureB
if exists (select * from sysobjects where id = object_id(N'[dbo].ProcedureC') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].ProcedureC
if exists (select * from sysobjects where id = object_id(N'YourLogTable') and OBJECTPROPERTY(id, N'IsTable') = 1) drop table YourLogTable
if exists (select * from sysobjects where id = object_id(N'YourTestTable') and OBJECTPROPERTY(id, N'IsTable') = 1) drop table YourTestTable

this will run the above procedures for four test cases:
- fail in A, YourTestTable has no data in it, YourLogTable shows log info for A
- fail in B, YourTestTable has no data in it, YourLogTable shows log info for B and A
- fail in C, YourTestTable has no data in it, YourLogTable shows log info for C, B and A
- all work, YourTestTable has data in it, YourLogTable has no data in it
code here:
DECLARE @ReturnValue int
DECLARE @ErrorMsg varchar(1000)
print '###########################################################################'
print 'will error out in A - should log A>>> EXEC ProcedureA 1,''abcd'''
delete from YourTestTable; delete from YourLogTable;
