Hi newbie here ! This community has been very helpful so far, but now I'm stuck on an order form I'm working on.
Here's the problem..

I have a listing of participants each one can check a box partcipant_1_checkbox either 1 2 or 3

But I need to add a value to each

1 = 5.25
2 = 9.00
3 = 11.50

So far I can get the amount ordered into the total amount from each participant box eg 1 2 or 3 by using this in the custom calculation script box

var a = this.getField("partcipant_1_checkbox").value; // variable for the estimated value
event.value = a;

But i need the amount ordered to show up as a value eg 1 should be £5.25

as you can see from below ... not a clue!!!

var a = this.getField("partcipant_1_checkbox").value; if ( partcipant_1_checkbox = 1)
event.value = 5.25; //
var b = this.getField("partcipant_1_checkbox").value; if ( partcipant_1_checkbox = 2)
event.value = 9.00; //
var a = this.getField("partcipant_1_checkbox").value; if ( partcipant_1_checkbox = 3)
event.value = 11.50; //

Hope someone can help

With thanks
Rusty

Some basics about check boxes.

1. The box can be checked or unchecked by a mouse click or space bar press.
2. A group of check boxes forms an 'exclusionary' group
3. Each check box in an exclusionary group should have unique value
4. If a check box in an exclusionary group is checked only boxes with the value of checked box will be selected.
5. Check boxes have a value of "Off" when all are not selected.

Let's look at your code that works with comments:
// get the check box object for the 'participant_1_checkbox' objectvar a = this.getField("partcipant_1_checkbox");// set the value of this field to the value of the 'participant-1_checkbox'event.value = a.value;

Note that the 'set' operator is '='.

One of the equality operators is '=='. So one could use:
// value if 'Off' or not an expected valueevent.value = 0; // set default value// get the 'participant_1_checkbox' field objectvar oCheckBox = this.getField("partcipant_1_checkbox");// check the value of the field objectif ( oCheckBox.value  == 1)event.value = 5.25; // set field value if (oCheckBox.value == 2)event.value = 9.00; // set field value if (oCheckBox.value == 3)event.value = 11.50; // set field value

Now if you assign the monetary value to the check box and then use the not equal operator, '!=', then your code could be simplified to:
event.value = 0; // set default value// get the 'participant_1_checkbox' field objectvar oCheckBox = this.getField("partcipant_1_checkbox");// test if not 'Off' valueif(oCheckBox.value != 'Off") {event.value = oChekcBox.value;}

Not the default value is set at the start of the script. This will result with the field value only being updated when a known value or an expected value is found and not forced unconditionally at the end of the script.

Thankyou for all your information, very very helpful indeed. I'm completely new to Java Script so it is starting to sink in slowly.

I'm using a exclusionary group of radio buttons for each participant 1 2 & 3. After the third radio button value of £11.50 (which now works thanks to you guys) there is another box in which the participant add an additional order of 1 to as many as they like @ a value of £3.00 each but only if they have checked radio box 3 @ 11.50. Is there a way of setting this box so no number may be added untill check box 3 has been checked.Thank you in advance
