Hi,
I have a problem trying to replace data in the title tag of an mp3 file.
I have tried to find the gotchya (doesn't work on a Tuesday?) amongst the FAQs and forums, but not been able to find anything, which undoubtedly means that I am doing something incredibly stupid. Nevertheless, my problem is when I try to do the simple Replace Quick Action, I get 'formatted tags in 0 of 12 files' when I try to save it.
Similarly (I think), If I type **%title% is "Captain Fantastic and the Brown Dirt Cowboy [#][Live]"** into the filter, it doesn't select anything.
Can someone please explain what I'm doing wrong?
MP3Tag 2.49 under Win7 SP1 64-bit

For the repalce action, the field name is "TITLE", not %TITLE%"
TITLE is needed when the field itself it meant.
%title% instead is the value of the TITLE field.
For the filter, you have to write filter exressions in capital letters. So use "IS" instead of "is".
