Conditional formatting of numbers only in event value script (PDF forms)

Another question, getting greedy I know,

Is it also possible to change the font size for spans[1]?

I tried mimmicing the code with the command 

spans[1].fontSize = 16; 

after the bold command but to no effect and it removes the bold.  Default font size for this field is 9pt in Times New Roman.

Try something like this:

Place the conditional script in the number field and have it output to the text field. You'll need to use an array() to get the conditional formatting you want.

I created a number field formatted as a number and created a text field with no formatting. In the number field I added this custom calculation script:

var v = this.getField("Number1").valueAsString;

var spans = new Array();

spans[0] = new Object();
spans[0].text = "Words: ";
spans[0].fontWeight = 400; // normal weight

spans[1] = new Object();
spans[1].text = v; // insert the value we read from the field
spans[1].fontWeight = 800; // bold

var f = this.getField("Text16");
f.richText = true; // make sure we are dealing with a rich text field
f.richValue = spans;

The array gets written to the text field as richtext.

Hope this helps.
