This method works for setting a standalone parameter value, but when I tried adding the tableIndex so I can update a parameter in a specific row it fails.

Element setelement = engine.FindElement(dmaID, elementID);
setelement.SetParameter(parameterNumber, parameterValue, tableIndex);

tableIndex is a string according to this document but maybe this is unrelated.  My question is how do I pass the table row index with the SetParameter method.  I'm using the generic table driver for my test and the index of the row is f4b749d8-5794-4b19-bce8-81fe1af17134 which I provided but I'm getting an error...
