Yes , it is possible.
Have you tried writing your own script yet?
No, but only because I don't really know how. Is there like a YouTube video or something?
You could put the following script in the Custom Calculation Script of the line total that refers to the relevant line checkbox, and then have a "total" at the bottom, and that sums each line that has been 'checked' - obviously the export value of the checkbox might need changing from the example below, as will the pricing and field naming;
event.value = this.getField("Checkbox1").value == 1 ? "100.00" : "";
Thank you for your help!
You actually don't need to use any scripts for this. Just set the price as the Export Value of each check-box and then select them directly in the Sum function under the Calculate tab of the total field.
