@Luis_Andres_Herrera - wow, that's one massive beast 
It's best to use the Snippet Exchange when working with such big snippets.
I've placed your version here:
First of all, I noticed duplicate entries in your dropdown menus.
For instance, notice how "adecuado funcionamiento" shows up twice in the example below.
{formmenu: name=fndye; adecuado funcionamiento.; neumotaponador con fuga.; fibrobroncoscopio: test de fugas (+).; default=adecuado funcionamiento.}
This is happening because you're adding the item twice (one of them as a default). You don't need to do that. Here's what it should look like:
{formmenu: name=fndye; default=adecuado funcionamiento.; neumotaponador con fuga.; fibrobroncoscopio: test de fugas (+).}
Next, I don't understand why you have an {if} command at the top. I'm referring to this:
{if: `Hora VA` <> ""}{endif}{formtext: name=Hora VA; cols=9}
What is it supposed to achieve exactly? Nothing changes regardless of whether I enter text in the "Hora VA" field or not.
Let's tackle these points for now. Then we'll move on to the rest.
