I need some help with a form. I am trying to learn XML and at 67 yrs. old it is difficult and I have little patience for hours of research. So a simple and concise explanation is required, please. 
I have just started to use LiveCycle ES2 for an Adobe form in the last 2 days. This is all very new to me. I have the form completed but would like to have one text input display only uppercase, <picture>text(A9A 9A9)</picture>, for a Canadian postal code. Where would I put and what code would I use to convert the Alpha to upper in my XML sheet. I have attempted to find an answer and see a number of options that I have no idea how to use.
I could most certainly could go without this but I am a fussy old man, ask my wife.
I can add the complete <field> syntax if need be if that would make the explanation any easier.
TNX, Bob
