Everything else being good - try this.
Open the 'Text Change' module and click the 'on' or 'play' symbol to the top right of the module.
Go to your 'Media Set' and click the last tab on the right, tab number nine with the odd symbol (what is that!?).
Click on the large 'Text' option to make that layer a Text layer.
Go back to the 'Text Change' module and enter the words or sentences you want to use, remembering to put a comma (
, ) between each word or sentence.
Don't put a comma after your last word or sentence as this will create a 'blank' word. This can of course be useful sometimes.
Click the large 'Play' button within the module itself.
It should now be working.
If you add words or sentences during operation you may need to click this 'play' button off and then on again to re-trigger the module and show your changes.
anyway , all the modul which i download from update is can work without editor , right ?
Correct.
Modules don't need to be edited in order to work.
The editor is there for you to create your own modules.
