Batch rename with user input and sequential number

Hi Everyone, I am trying to batch rename files that are in a folder on my desktop but whatever I do it is just not working! I have attached a screenshot showing what I am trying to do. I am basically trying to batch rename my files with the following format: BaseFilename-01.jpg / BaseFilename-02.jpg

It will be interesting to see where I am going wrong as I really want to learn (very new to KM).

Kind Regards,

Margate : )

Finally worked it out! Well I am quite sure my solution is not "correct" but it works for me and I am updating here in case anyone else finds this handy and will hopefully save them having to spend about 4 hours trying to work it out like I did lol..
