Having searched the forums I thought I’d worked this out – didn’t, haven't – messed up.
Have title tag for example
“Happy Birthday, Sweet Sixteen - Neil Sedaka”
Want to remove “ - Neil Sedaka”
Created action
Field = Title
Regular Expression = (._)-(._)
Replace matches with = $trim($1)
Using this action title is renamed
“Happy Birthday”
Seems to work OK if there is no “, “ in title
i.e. “Happy Birthday Sweet Sixteen - Neil Sedaka”
Returns “Happy Birthday Sweet Sixteen”
Need to be shown the error of my ways – big please

There's currently a problem when a comma enters a function in the RegEx Action.
But you can just use a different expression that has the same effect, like
RE: \s+-.+$
Replace:

Thanks for that.
Luckily didn't mess up too many. This should mean that I don't mess up any more.
Cheers

Man, I am really trying to understand this. I am trying to trim the last 7 characters from my album field. I have been using a regular expression to trim the first three characters of the title like so:
Field = Title
Regular Expression = ^.{3}
Replace matches with = ""
Very simple and straight forward. I thought that it would be just as simple to do the last 7 (not trailing spaces " [YYYY]" with $.{7} . This obviously is not working. I am not good at scripting, I have been reding the forum for about an hours and I am just not getting it.
Thanks in advance.

You could have seen from my post that the end sign $ is also acutally put at the end!

Damn I hate it when it is something simple like that. Thanks for the help.
