Script for auto Typescales - paragraph styles applied to some sample text but not all?

Okay slightly better but still not working  - as later I will make it so that a user can add more than 5 styles so there could be 7 for example so the names will be added etc

this code now styles up to 4 but not 5 

There must be something I am doing wrong 

Many thanks

// Define your script as a function
function myScript() {
