Hashtable chart

# This simple hashtable chart produces the error:

#At line:5 char:70 + add-member -inputobject $aItem -membertype NoteProperty -Name <<<<  $entry.Key -value $entry.Count

# What am I doing wrong? Thanks.


# Test for snapin already registered with session; add it if not.

foreach ($i in 0..$NUMITEMS) {

add-member -inputobject $aItem -membertype NoteProperty -Name $entry.Key -value $entry.Count  # or $entry.Value


I've just left 2 lines of interest...  I'm not sure where you get $NUMITEMS.  Would that be this instead:

foreach($i in 0..$names.count)

That may still leave you with an offset of 1.

For your add-member command, I believe you should have:

...-name $entry.keys -value $entry.values
