Hello @grayhats
You have configured invalid dependencies in the fieldname30 field (you have not entered the value to compare). The calculated field fieldname25 was configured as editable, but you have not ticked the checkbox to not evaluate its equation when the value is entered manually. So, entering the fieldname25 value evaluates the equation of fieldname24, but as you use the fieldname24 in the equation of the fieldname25, both equations cause an endless loop evaluation.
Best regards.
