Hello,

thanks for your reply and attempt to help me out.

Well, the remove button is obviously not needed at all, thanks for pointing that out.

Your code is working so far, however it is not working as i intend it to.
Whenever an item from the listbox is selected and added to the contentPreview textbox, i want it to display a much longer sentence, as the words in the listbox are just placeholders for what actually should be displayed in the textbox.
I dont want to have the whole sentence displayed as a listbox item, so i would need the contentPreview to change to a certain sentence or sentences, depending on what items are selected.

For example:

• The first item in the listbox says "Housing Gasket".
• The sentence that gets written in the contentPreview Textbox should then be something like "[manufacturer] [type] [size] Housing Gasket replaced." (the variables in the square brackets are coming from selections the user made in other parts of the document, i just showcase this here, so that you can see why i can't display the whole text as a listbox item, because they are pretty long and would not fit in the listbox.)
• So if the user selects multiple items from the listbox, each item should refer to a specific sentence, which should then be displayed in the textbox. I hope that makes sense.

Is there a proper way of doing this?
