I know how this is going to sound, but I find the need to ask anyway. I was wondering if I can create a field that will 'get' the value of another field, and then change its own value accordingly.
if Field 'A' = 13, then Field 'B' = 1.
Create a custom calculation script on the field you want to change, with the following:
a = this.getField("a").value;
if (a==13) event.value = 1;
