Shade whole row on specific term

Dear Experts:

below code searches for a specific term in a table (input by means of an inputbox) and shades the whole row grey where this term is located.

The code works fine but ...

... although I have indicated '.MatchWholeWord = True', more rows get shaded as required.

Example: Inputbox Input = "Set"

If a cell contains the term "My Set" or "Configuration-Set" or "Set Configuration", these rows also get shaded, but I only would like to get those rows shaded where the cell contents is just "Set" and nothing else.

Help is much appreciated. Thank you very much in advance.

Regards, Andreas
