how to give an X a point value in text boxes

The value in TOTAL may be computed incrementally, based on each change in the value of the G*. The value in #WRONG may be computed incrementally, based on each change in the value of NG*. The change may be brought about by a field event such as MouseUp or Blur. For example if G0 changes from ‘’ to ‘X’ then 5 is added to the value of TOTAL, and if G1 changes from ‘X’ to ‘’ then 5 is subtracted from the value of TOTAL. Here is an example codes for the MouseUp event for text fields G* and NG* respectively

switch(event.target.value) {
  case 'X':
    event.target.value = '';
    this.getField('TOTAL').value -= 5;
    break;
  case '':
    event.target.value = 'X';
    this.getField('TOTAL').value += 5;
    break;
  default:
    event.target.value = 'X';
    this.getField('TOTAL').value += 5;
  break;
}

switch(event.target.value) {
  case 'X':
    event.target.value = '';
    this.getField('#WRONG').value -= 1;
    break;
  case '':
    event.target.value = 'X';
    this.getField('#WRONG').value += 1;
    break;
  default:
    event.target.value = 'X';
    this.getField('#WRONG').value += 1;
    break;
}

The document "Computing Sums Incrementally and Automatically" is a reply to your question with more details. It contains three sample form applications: the first uses text fields for G* and NG* and attaches the code above as a MouseUp event to every text field, the second uses text fields for (G* and NG*) and attaches the code above as an OnBlur event to every text field, and the third uses button fields for G* and NG* and attaches code similar to the above code as a MouseUp event ot every button field.

I would check boxes or radio buttons and assign an export value of 5 to the second column and 0 to the first column export value. Then you can just sum the value of the check box/radio button fields. For the "WRONG" field using the first calculation option of "Field is the sum of the following fields" and selecting the check boxes/radio buttons and then use the "Simplified field notation" to calculate the "TOTAL" field by subtracting the "#WRONG" field from 100. Also I would not use a symbol as the first character of a field name. I would also rename the second column form the "NG#" to "G#", that will make the check boxes/radio buttons act in a mutually exclusive manner.

There many free tutorials about creating forms free ftom Adobe and you should watch/read them.
