Odd RoboCopy behavior in script

i using code robocopy , getting odd behavior.

robocopy $sourcefolder $destinationfolder /mir /mt /copyall /r:5 /w:5 /log:$env:temp\pxcopy.log /ns /nc /np | out-null

when hard code source , destination works right every time. however, when use source , destination paths have been pulled xml, robocopy returns 0 (no new or changed files copy) , nothing, when verifiably not so. code using process xml function working 15 other tasks have need paths, new robocopy task has issues. 

fwiw, work fine when copying empty folder, it's when trying compare mirror fails.

also, working ps 2.0, , not in position require newer version, if issue.

any thoughts?

thanks!
