I have the need to run a simple calculation on a form. The first three elements that may/may not factor in a value are checkboxes. I'm not a developer so this process is fuzzy for me. I'd like to know what I add to this statement to include/exclude their value whether or not it's checked. event.value = ( this.getField("CheckBox.14").value +
this.getField("CheckBox.15").value +
this.getField("CheckBox.16").value ) -
this.getField("Text5").value +
this.getField("Text8").value;
 
Thanks!

First, checkboxes do not have a numerical value so they can't be used like this. I don't know exactly what you are trying to do but the calculation script could be structured like this:

event.value = 0;if(this.getField("CheckBox.14").isBoxChecked(0))event.value += 1; // Add one if(this.getField("CheckBox.15").isBoxChecked(0))event.value += 1; // Add one if(this.getField("CheckBox.16").isBoxChecked(0))event.value -= this.getField("Text5").value + this.getField("Text8").value; // Subtract text Fields
This is one way that check boxes can be used in a calculation.
