Inconsistent String Variable

[namauto]

So I'm trying to take a file name from an array, and open the file in a program. Sometimes it works, sometimes it doesn't, with no changes to the code. I made a MsgBox so that I could make sure the file name was right in the array (and it is, consistently), but then when I try to use it to open the file, it says the file doesn't exist, and there are a few characters missing from the file name. Its different characters at different times. I have no idea what's going on, this worked earlier for me, but now it doesn't, and I have made no real changes.

Please help.

Dim $fileNum
Dim $fileList
$fileList = _FileListToArray("...\SC", "*", 1)
$fileNum = $fileList[0]
Run("...\Charles.exe", "...\Charles\")
WinWait("Charles 3.2.1 - Session 1 *")

$fileName = $fileList[3]
Call ("charlesExport", $fileName)

Func charlesExport($fileName)
    $fileNoExt = StringSplit($fileName, ".")
    $charlesName = "Charles 3.2.1 - "&$fileNoExt[1]
    MsgBox("", "", $fileName)
    Send("^o")
    Send($fileName)
    Send("{ENTER}")
EndFunc

Use the "raw flag" for Send($fileName, 1) if there is punctuation in the file name, like "+" that would be interpreted as a metakey like "shift".
