 * I want to add field1 to field2 but only if field1 is in minus
    for example: if
   field1 = **-5** and field2 = 2, field3 would display 7 but if field1 = **5** 
   and field2 = 2, then field3 would display 2
 * how can I do that please?

 * Hi,
 * An equation to get the waited result would be:
 * (fieldname1 < 0) ? ABS(fieldname1)+fieldname2 : fieldname2

 * Its not working. And there is no zero showing before adding data.

 * Hi,
 * Your form includes many calculated fields with complex equations. Please, select
   the calculated field, and uncheck the option for optimize the equation.
 * Best regards.

 * The minute I unchecked “optimize form equation”, it worked like a charm.
    Many
   thanks indeed. By the way, what does that option do?

 * Hi,
 * This option try to avoid the chain of equations when the equation of a calculated
   field includes other calculated fields; but with complex equations the process
   of optimization can fail.
 * Best regards.
