Format bold text in field and putting some text on new line - Help!

Question

I am lost.  I found the rich text formating item to click.  But after that, I don't know what to do next.  I want to bold some characters and I want some reponses on separate lines as I asked previously.  As to spans and the commands - I have no programming experience.  I have just been using what George has given me.  It has worked well, but I just need the bold text in some of the field text to be printed and I need some items to be on separate lines.  But I have no idea where to put the information you are saying about spans and I do not know the script to use to bold text or to start text on new line.  Am I to insert it in the calculation box of the text box?  Sorry to be so lame, but I am void in programming skills.  Help!
For example, here is the script.  In aISOreq{0], if I want to bold "Patter#1 Check:", where do I put the span and what script do I use to say to bold it.   Could you give me an example, please.  Also, if I want to put "a. Medications on weekend?" on one line and "b. Activities on weekends? Types of activities? Supervision? With who?" on the next line, where do I put the span and what script do I use to say to put on separate lines?  Could you give me an example for this also, please.  I have literally just used the scripts George has given me and they work great - but that is all I know how to do.  Thanks.

Answer 1

Look at the reference of the richValue property of the Field object. It contains a couple of examples of how it should be done. Also read the reference of the Span object.
