I'm looking to alter the text that displays at the checkout.
For example I'd like "Grand Total Incl. Tax" to change to "Total"
I've tried editing the files in /app/locale/en_US/ such as Mage_Tax.csv but it hasn't seemed to do anything.
I changed the second column to the text that I wanted, and left the first column as the original "Grand Total Incl. Tax".
What am I missing?
A much easier alternative to that would be to enable Translate Inline via the Admin Module.
Now, refresh the frontend and you should be seeing red dotted boxes around those terms. Mouse over them and click the book icon – this will open up the edit form in a lightbox. Make the necessary changes and save it and your job is done. As simple as that !!!
There is another way:
You add prefix module name before your text. For example:
"Mage_Tax::Grand Total Incl. Tax", "Total"
=> Mage_Tax:: (text)
Hope this works for you.
