I'm new to Acrobat forms; just finishing my second, using Acrobat 8. I have one field where I want to limit user entries to one of three letters. In other words, they can only enter C, N, or H in this particular field. Is there any way to do this? I already have a column of this field created and formatted, and am hoping I don't have to start over and replace it with a radio button.
Thanks!

Thank you, George! I'm using Acrobat, not LiveCycle. Writing JavaScript is, unfortunately, not in the form field of my knowledge. I searched the Net for one I could copy and paste, but couldn't articulate my search terms well enough.

// convert entry to upper case
event.value = event.value.toUpperCase;
// see if entered value is a 'C", 'H', or 'N'
if(/^CHN$/.test(event.value)){
// issue an alert
app.alert('Only "C", "H", or "N" are valid entries.\nPlease reenter.', 1, 0);
}
You could also just use a custom keystroke script to only accept those three letters.
event.value = event.value.toUpperCase();
if( /^[^CHN]$/.test(event.value) ){
event.rc = false;
app.alert('Only "C", "H", or "N" are valid entries.\nPlease reenter.', 1, 0);
app.beep();
}
Or just use a combo box with the trhee choices.
event.value = event.value.toUpperCase;
// see if entered value is a 'C", 'H', or 'N'
if(/^CHN$/.test(event.value)){
// issue an alert
app.alert('Only "C", "H", or "N" are valid entries.\nPlease reenter.', 1, 0);

In Acrobat you write a custom JavaScript with all the control.
In LiveCycle Designer, you can chose either FormCalc or JavaScript and write a script the results in either a logical true for passing the validation or a logical false when the validation fails. For any validation method you also need to enable an option for the field and enter the text for the error.
