hi , micker!
first of all i should tell you that my flexicontent is in french language pack (which is not complete...)
I search a little bit and found that i have to look for the strings into the en-GB.com_flexicontent.ini
then put them into mytemplate.
For instance, i want to turn the word "items" into "resultats" (french) in one of my templates, but still keeping the word "items" for the other templates.
It worked.
my problem is it, i want to change the strings for the labels in the submit form, and it doesn't work
