Conditional Field filled with value Token support

hi

does this module supports tokens?

I have a content type with the title BOOk, it is several taxonomy fields ,one of them is called serial and have one of the values 1001,1002,1003,...for example 1001

I add a Text field to comment field,it was filled by the user.
then add conditional field in comment fields :
show comment field(text area) if Text field has value, and chose regular expression
now,I want insert token of the serial field from current node.

what's token?

is better way for my request?

thanks
