Hello @aymericfb
Your website responds with a “Coming Soon” page. However, the information you describe is usually related with an endless loop.
First, I’ll try to describe how the plugin works. If you vary a field’s value, the plugin checks all the equations affected by this field and evaluates them. The evaluation of the equations provokes a change in the values of the calculated field too. So, the process is repeated multiple times until no field varies its value.
Once described how the plugin works, I’ll try to indicate the possible causes for the endless loops.
* If you use a field in its own equation, this generates an endless loop.
* If you use field A in the equation of field B and field B in the equation of field A, you are generating an endless loop. The chain of fields could be longer, field A in the equation of field B, field B in the equation of field C, field C in the equation of field A, closing the circle.
* Something similar can happens with the dependencies.
In short, if your form is freezing, please, check the possible endless loops between the equations entered in the calculated fields.
Best regards.
