After discussing the issue, it was determined that the problem was due to the function "slider one" being defined inside a Webflow dot push block. This meant that it was only accessible within that specific block and was not appended to the window object. On the other hand, the second script added "slider one" to the window object, making it globally accessible.
To resolve the issue, it was suggested that David remove the "window dot" part when using the local version of "slider one" in the code below. By doing so, he should be able to use the local version instead of the globally accessible one.
The meeting concluded with David agreeing to implement the suggested changes and seeking further assistance if needed.
