I have a total_amount field and another field with the number of quotas.
I created a math column that divides total_amount by quantity to get the value of one quota.
User can enter the number of quotas, I calculate it amount to pay and add a row in the quotas information tab.
Then I have another math column that gives to me the balance or the number of quotas available.
My point is that, suppose that the user entered the number 3, then I calculated and go!
The next time, if the user opens some record, the number entry field is showing the last number.
I´d like to open with 0 or empty. Is it possible?
I appreciate it in advance.
