format auto fill text to all caps

I'm not sure if there is a way to do this or not, but here is my situation and question.

I have created a form that auto-fills a user's name, which is pulled from the LMS system (Absorb LMS) so it will give them a "certificate" when they complete a course. The PDF form I have created is the certificate. What I want is for their name (which is uppper and lower case in the system) to come out as all caps on the PDF certificate.

I've tried the other scripts such as

event.value = event.value.toUpperCase(); and

event.value = event.value.toString().toUpperCase() ; and even

if(!event.WillCommit)event.change = event.change.toUpperCase() ;

but I these don't seem to work and I think it could be because they are not typing in their name--it is being autofilled with information that is pulled directly from the system.

So my questions are

1) is there actually a way to make this happen?

2) if so, what is the script? (I don't know anything about writing my own scripts, but am quite adept at copy and paste. 

Any direction in this area would be appreciated.
