Just a thought even though you no longer need it Alex, but a couple things to check on the variable - was it dim'd properly, also we run into issues a lot with something above setting a variable/location that it is looking for as something unintended so although you code may be right a run before it sends this string looking in the wrong direction.
My run-ins with VBA though stem from using Excel to interface with a simulation program.
