InfoPath Dev

I have a rule set on field1 which states if field1>0 and field4=/=0 then set field2's value to field3/field4. The rule works fine, however, after field2's value is calculated the first time, and the user changes the values of the other fields, field 2 doesnt update. I know when you set a default value for a field, you have the checkbox that allows the formula to be recalculated each time, but when using the "set a fields value" function in rules, there is no such checkbox, and the values dont constantly update. Anyone know a workaround?

 You have to put the same rule on all the involved fields. So - same rule on field1, field3 and field4. Make sense?

Worked, thank you so much!
