Business rule from page parameter

Hi community,

I'm trying to activate a business rule - manadatory field - from a page parameter but I'm not able to do it.

I have a "Service" object to enable the system administrator to do some parametrization, in this example it has a boolean "Is Type of Cut Input?"

When this is set to true in the "Product Development" object if I create a "product development" of with a Service that has the "Is Type of Cut Input?" then the type of cut should be mandatory.

I've passed the "Is Type of Cut Input?" as a parameter into the page:

but then, when I build the business rule, it is not applied on the page:

Am I missing something? is there a way yo get this to work without code?

Thanks

Luis
