Powershell , Get-content, Import Txt File into an array

Hello,

So i am trying to mimic an array that works, by import a txt file containing info.. but it is not working.

This works....

# Filter for an array of values IE: choose muipliple items.... in one column
$xlFilterValues = 7 # found in MS documentation
#filter for column
$FL = @("Item1", "Item2", "item3") 
$rng=$Worksheet.cells.item(2,38).entirecolumn
$rng.select | Out-Null
$excel.Selection.AutoFilter(20,$FL,$xlFilterValues)

This does not work..

Txt file contains  Item1, Item2, Item3

Here is the code that does not work, What am i doing wrong??

# Filter for an array of values IE: choose muipliple items.... in one column
$xlFilterValues = 7 # found in MS documentation
#filter for column
#$FL = @("item1", "item2", "item3") 
[array]$FL = Get-Content C:\Test\Row20aa.txt
$rng=$Worksheet.cells.item(2,38).entirecolumn
$rng.select | Out-Null
$excel.Selection.AutoFilter(20,$FL,$xlFilterValues)

Thank you in advance, Please help
