powershell script that reads from excel and updates annotations

Well, darn. not working for me as yet. Hopefully something simple.
I have a csv file with 2 columns, the first  cell a1 has "VMName"(no quotes) in the cell below it ,in a2 a3 and a4 are server names, lets say server1 server2, etc.
in b1, the cell has "value"(no quotes)  in it, since this is actually what is getting changed .
It is saved as anno.csv, in the same directory as the script.
When I open it in excel, I see the 2 columns and the data in them.
An administrative ps session is opened in that directory.
When I run this:

Import-Csv -path C:\scripts\anno.csv | ForEach-Object {
                Set-Annotation -Entity $_.VMName -CustomAttribute "location" -Value $_.value
}

Select allOpen in new window

I get this, which looks to me like the command is not getting the server names:

Set-Annotation : Cannot validate argument on parameter 'Entity'. The argument is null. Provide a valid value for the argument, and then try running the command again.
At C:\scripts\update-anno-from-csv.ps1:2 char:25
+     Set-Annotation -Entity $_VMName -CustomAttribute "location" ...

Open the csv file in Notepad or any other text editor and verify the format, and/or just run
Import-Csv -path C:\scripts\anno.csv
It could be that your standard delimiter is not a comma, and Import-Csv expects a comma by default.
If the delimiter in the csv file is, for example, a ";", just add the parameter
-Delimiter ";"
to the Import-Csv command.
Import-Csv -Path C:\scripts\anno.csv -Delimiter ";"

So the issue is the csv file, which I am also seeing when I just import it, the top "headers" are run together,
I receive  a spreadsheet with two columns, which I save as anno.csv.
I guess that is not sufficient to create it in the correct format, if I open it in notepad there is no commas or any delimiter.
