Isn't that what you want to do?

Function CheckForspaces()
    txt$=TextFieldText$(SiteNameField)
    ln% = Len(txt)
	For i = 1 To ln
		If Mid(txt, i, 1) <> " " Then
			NoName = False
			Return
		EndIf
	Next	
	Notify "You MUST give it a name!"
	NoName=True
End Function

(I have supposed NoName is a global variable.)

Or even simpler:

Function CheckForspaces()
    txt$=TextFieldText$(SiteNameField)
    NoName = (Trim(txt) = "")
    If NoName Then Notify "You MUST give it a name!"
End Function
