Dim statement for Split array

[Jennifer Murphy]

I don't understand why this code works:

Dim BlueLite As String          'Light blue RBG values
BlueLite = "219,229,241"        '.
Dim RGBVals As Variant          'Array for indivicdual RGB values
RGBVals = Split(BlueLite, ",")  '.

But this code gets a runtime error '13' (Type mismatch):

Dim BlueLite As String          'Light blue RBG values
BlueLite = "219,229,241"        '.
Dim RGBVals() As Variant        'Array for indivicdual RGB values
RGBVals = Split(BlueLite, ",")  '.

Aren't the parens required when declaring an array?
