Correction to my last post (my apologies):

I am hoping someone could assist me with this.
I've created a word form (to also be used on mobile); it has multiple content controls (text, checkbox, dropdown lists, date picker). The form is protected to allow form filling only (with no password). This is what I need it to do:

1. on open, all the content controls fields values needs to be blank...although, I suppose it can be done once the user submits it?
2. I want the form to check the values to make sure they are the proper format. for example, in the name field, I want to make sure there are no numbers entered and, of course check that no field value is blank. Is there a way to check each field as the user enters them? or, better yet set the property for each field( which i tried to do, but not able to find the option to do so)
3. once the form is completed, there is a section to sign it electronically (which only worked for me in unprotected mode)... Is there a reason for this?
4. I then want to give the user the option to submit or print the form
