I have a series of check boxes, 5 of them to be specific.  I then have a radio button for member or non member and one more check box for additional service fee.  I then have a total text box.

What I would like to do is have the script calculate the total off of the radio button value they are set to 110 and 130.  then multiply the number of check boxes checked by 50$ and add the additional service fee to the total if checked.  I would like this amount to show up in the Total value text box.

I am not sure how to do the radio buttons. would I do 2 if statements? one for if(this.getField("Naturalist_Membership").value == "110" then ... and one for if (this.getField("Naturalist_Membership").value == "130" then ...?

I would use the following as the calculation script for the result text box:

// Count the checked check boxes
var CB_Count = 0;
var baseName = "CB.";
for (var i=0; i<5; i++)
{
    if (this.getField(baseName + i).value == "Yes")
        CB_Count++;
}

// get the fee
var fee = this.getField("Naturalist_Membership").value;

// store the result in this text box
event.value = (CB_Count * 50) + fee;

Here is my exact code. I will also attach my PDF version.  I can not get it to display any text in the textbox. Please help! Thanks.

// Count the checked check boxes
var CB_Count = 0;
var baseName = "yn_";
for (var i=0; i<9; i++)
{
    if (this.getField(baseName + i).value == "Yes")
        CB_Count++;
}

// get the fee
var fee = this.getField("Naturalist_Membership").value;
var extra_fee
if (this.getField("yn_extended").value == "Yes")
  extra_fee = 25;
 
// store the result in this text box
event.value = (CB_Count * 50) + fee + extra_fee;

There are a couple of things that are not correct with your code:

1. Your fields are named yn_1..yn_10, but your loop goes over the fields yn_0..yn_9
2. You must have changed the export value for the checkboxes - the default is "Yes", but you are using "On". You need to change the script to reflect that as well.
3. I would initialize the variable extra_fee to 0 (and the line needs a ";" at the end).

Try this:

// Count the checked check boxes
var CB_Count = 0;
var baseName = "yn_";
for (var i=1; i<10; i++)
{
    if (this.getField(baseName + i).value == "On")
        CB_Count++;
}

// get the fee
var fee = this.getField("Naturalist_Membership").value;
var extra_fee = 0;
if (this.getField("yn_extended").value == "On")
  extra_fee = 25;
 
// store the result in this text box
event.value = (CB_Count * 50) + fee + extra_fee;

Ok awesome that works! the only thing is how do I get it not to say 0Off0 in the total text box.  I would be ok with it just saying 0

Ah... I see the same behavior here. Something must have happened when I copied/pasted the code. I am looking into it.

Found it...

You do not have a default state for the radio button. I assume it's wrong to not have anything selected for the membership level, so I would just define a default state (e.g. non-member) and that will take care of this problem. What you are seeing is that in the case of no selected option, the control returns "Off" instead of a value. If you do want the current behavior, just add the following like after you determine the fee:

if (fee == "Off")
    fee = 0;

This will force fee to a zero, and the total will be correct.

As I said, I would change the behavior of the radio button. If you still want "0" to be displayed when nothing is selected, just make a final check after you calculate the total:

var total =  (CB_Count * 50) + fee + extra_fee;
if (CB_Count == 0)
    total = 0;
event.value = total;
