Calling a Function Within a For-Each in Powershell

Question

Error:
Unexpected token 'in' in expression or statement.
At :line:1 char:22
+ ForEach-Object ($i in  <<<< $fs_size_info) { $i.Name.Name, GetGB($i.Sum)  }
Code:
foreach ($i in $fs_size_info) { $i.Name.Name GetGB($i.Sum) }
If I omit the function from inside this foreach, it works perfectly, and I can access $i.Sum within the foreach as well. The problem arises when I try to call a function from inside the foreach. GetGB simply returns a more readable format e.g. GetGB(1024)
will return "1 K" etc...
I don't understand what I'm doing wrong, unless you cannot call a function inside a foreach statement.... am I missing something?
Thanks

The code you've posted and the error message don't seem to go together, unless the line before that "foreach" keyword happens to have ended with a pipe character.  There's a difference between how you use the foreach statement (help about_Foreach)
and the ForEach-Object cmdlet (help ForEach-Object).
Either way, it looks like inside the loop body, you've got two statements:  ($i.Name.Name) and (GetGB($i.Sum).  Those statements need either a line break or a semicolon between them.
