File Renaming Question using exif filename

Hello,
I am new to this and would appreciate some assistance.

I am attempting to use the New Name Renaming Method and I am using the following-

<Img Year>-<Img Month>-<Img Day> <Img Hour>h<Img Min>m<Img Sec>s<Img SubSec> <ExifTool:FileName>

I am getting this as my new file name.....
2023-10-07 17h13m04s80 DSC_5664.JPG.JPG

the .JPG.JPG at the end is the problem, I would like the newfilename to be 2023-10-07 17h13m04s80 DSC_5664.JPG
When i do the <ExifTool:FileName> is there a way to do a substr or rsubstr or something else to get what i want?

Thanks,
Dino

I think the easiest way is to add the Remove method:

Remove count: 3
Starting at: 1
Backwards
Apply to: Extension

Hi.
Replace: .JPG
Replace with:

Apply to name.
