>Index out of Range means one of the numbers inside [] is bigger than what actually exists. Since C# is zero based then m.Groups[2] must have 3 objects or .Captures[0] doesn't have any. I would put a breakpoint on that line and check each of those for the number of objects.

Hi,
The exception detail indicates that it's the Captures collection that's at fault....
