Nested PrevVal Not Returning Data When Data Exists

I'm building an Analysis Template and I have a PrevVal('Attribute Name','*') variable that is returning the correct Value at Evaluation, whereas I have two subsequent problematic variables:

PrevVal('Attribute Name',PrevVal('Attribute Name','*')) returns No Data

PrevVal('Attribute Name',PrevVal('Attribute Name',PrevVal('Attribute Name','*'))) returns Calc Failed


I've checked the specific Example Element and PI Tag for Value's, and value's do exist for these two intervals (I've also verified using nested PrevEvent statements as a few variables, to determine that the Value at Evaluation is correct, and it is).
