Exception when trying to FTP upload with a empty file set

I created a group and tried the following VB code:

SkipAction = %NewTRAKBuilds.IsEmpty%

which gives me an exception:

Invalid character
Line: 2
Char : 14

I then tried:

SkipAction = NewTRAKBuilds.IsEmpty

and get the exception:

Object doesn’t support this property or method: ‘NewTRAKBuilds.IsEmpty’
Line: 2
Char : 1

I don’t have NewTRAKBuilds defined as a variable–I would not know what type of variable to define it as.

Thank you,
