Excel 2007 :: Find And Format Text Within Chart Textbox Object?

I have a text box within a chart tab which is populated with text values from a worksheet within the workbook. That part works fine however i want to be able to achieve the following example:

Current Text: Component Name - Notes

if there are notes against the component name i want the name to remain in black and the notes to change to blue

Aim: Component Name - Notes

If there arn't any notes then for the component name and the "-" to change to a light shade of grey

Aim: Component Name -

There are 26 components, each on their own lines in the textbox so im thinking either a loop where the cell reference is variable eg. ("CY" & i) or using the .find with a variable.

My code so far is:

Code:
Sub Chart_Notes_NTCA()
Dim i As Long, j As Long, Counted As Long, Total As Long
Dim Ans As String, Notes As String
Dim Cht As Chart

[Code].....
