So I've known how to swap info between 2 fields. But this time I want ask about how to swap them but keep certain info. Inside my _Comment_ field, I've put some info and want to keep them from being switched to the _Title_ field.

Input Example:  
Title: Qiang Si  
Comment: Chance | From: ?SHOW

Desire Output:  
Title: Chance  
Comment: Qiang Si | From: ?SHOW

**| From: Info** is the one that I want to keep.

Can I achieve this? Thanks for the help.

Try an action of the type "Guess value"  
Source: `$regexp(%comment%,(.*) \| (.*),$1==%title% | $2)`  
Target: `%title%==%comment%`
