Hello Andres,

The <script> tag is disallowed in custom blocks due to security issues, so JavaScript cannot be directly embedded into custom blocks. I recommend looking into a Bootstrap carousel instead. Alternatively, at your own risk, you might allow <script> in as described in this forum thread.

You can enable the customHeader plugin to add the script there in the footer.
