Since it is a multi line parameter you would definitely want to use "parameter.asString" - "asValueString" is really more about numbers being presented fully formatted e.g. 20mm.

Try using "Revit Lookup" to make sure you are actually picking up on the correct parameter. Perhaps you are actually trying to get the value from an incorrect parameter or even a different element.

Doubling up of parameters named identically is not rare and can lead to lots of confusion.

Dear David,

In order to understand exactly what you mean and be able to research possible reasons for the discrepancy between the observed and expected behavior, Could you provide us:
· A complete yet minimal Revit sample model to run a test in.
· A complete yet minimal macro embedded in the sample model or Visual Studio solution with add-in manifest that can be compiled, loaded, run and debugged with a single click to analyse its behavior live in the sample model.
· Detailed step-by-step instructions for reproducing the issue, e.g. which element to pick, what command to launch etc.
