Make existing field required if action appears using in Adobe Text Tags

Hi Maciej,

There is no such function - you cannot change the property of a field (other than show/hide) based on a condition.  You'd have to have two fields (one required and one not) and show/hide them based on your condition.

{{[]c}}

{{f1_es_:showif(c!=checked)}}

{{f2_es_:showif(c=checked):required}}

Hope that helps,

Moe
