Error in Common Module

I have a large project that had multiple panels and views and after a lot of work I realized that I should have done multiple Activities each with its own screen.

So, I went back and started to separate everything and do it correctly as shown in the Beginners Guide.

I started to put all the common subs in a code module called Common.
I started with the code below and now I get this error:

---------------------------------------------------------------------
Here is the error:

B4A line: 8
Dim DBFileDir As String : DBFileDir = getSDCardPath 'File.DirDefaultExternal
javac 1.7.0_07
src\en\vtg\mim\common.java:115: error: cannot find symbol
_dbfiledir = _getsdcardpath(_ba);
^
symbol: variable _ba
location: class common
1 error
-----------------------------------------------------------------------

Here is the code in the Common Module:

Sub Process_Globals
'These global variables will be declared once when the application starts.
'These variables can be accessed from all modules.


Dim DBFileDir As String : DBFileDir = getSDCardPath 'File.DirDefaultExternal
Dim DBFileName As String : DBFileName = "MIM.db"
Dim DBFilePath As String : DBFilePath=getSDCardPath 'File.DirRootExternal

Dim SQL1 As SQL
Dim SQL2 As SQL
Dim SQL3 As SQL
Dim List1 As List
Dim TTS1 As TTS

SQL1.Initialize(DBFilePath, DBFileName, False)
SQL2.Initialize(DBFilePath, DBFileName, False)
SQL3.Initialize(DBFilePath, DBFileName, False)

End Sub
Public Sub getSDCardPath() As String

Dim iMount, iCRLF, iSlash, iAuto As Int
Dim fstab As String = File.ReadString("/system/etc/", "vold.fstab")
Dim Mount As String

Do While True

'get next line with mount point:
iMount = fstab.IndexOf2("dev_mount ", iCRLF)
If iMount < 0 Then Exit
iCRLF = fstab.IndexOf2(CRLF, iMount)
If iCRLF < 0 Then Exit
Mount = fstab.SubString2(iMount, iCRLF)

'get mount path:
iSlash = Mount.IndexOf("/")
If iSlash < 0 Then Continue
iAuto = Mount.IndexOf2("auto", iSlash)
If iAuto < iSlash Then Continue
Mount = Mount.SubString2(iSlash, iAuto).Trim

'return this one, if new:
If Mount <> File.DirRootExternal Then Return Mount

Loop

Return File.DirRootExternal

End Sub

I am still pretty new at B4A and I am a little lost in Multiple Activities.
Any help would be appreciated...
