Why did you start a different thread with the same name and a slightly different question?
More importantly, why didn't you attempt to do what I said? Please review:
Some questions:
1) Why didn't you replace the loop() call? Fix this.
2) Where is your for(listed_assets){asset(Asset); ... ... } loop? Fix this.
3) Why didn't you load an asset list? To do this, you call assetList(); Fix this.
