clear field when data validation fails

Great question!!! I am looking for the same!

The answer is in hidden fields. I realise that that sounds a little vague, but bear with me a minute ...

Step 1: For each "required" field, create a hidden numeric field with a default value of zero. Create a validation script for the required field, checking the hidden field and adjusting its value. If the hidden field was zero and the required field validates, then the hidden field becomes 1, if the hidden field was 1 (previously entered correctly)and the required field does not validate, then the hidden field gets a value of zero, otherwise it remains at 1.

Step 2: Create a form level variable which contains the total number of required fields. Each time you add a required field, manually increment this number.

Step 3: In the pre-save event, add a script which will add together the hidden field values from the required fields, compare it to the total number of required fields, and then allow or abort the save of the document based on the result.

From the help file description: "You can use this event to change form data immediately before the data is saved. For example, you can create a script on the preSave event to scan the data and display a reminder message to the form filler if certain required fields remain empty."

Logic would dictate that there should be a way of checking that all of the form validation is correct before allowing a "save" or "print" action, but I haven't seen one yet, hence the kludge above. If anyone knows of a better way, I'd be happy to hear it!

**************************************
Afterthought: Create a second hidden field on each required field, with a default value of 1. Now, in step 2, you can sum these fields instead of setting a form level variable, and you can turn 'required' on or off on a field just by changing this one value.

Hope that makes some sense and is helpful!
