I have created one field called usergroup on registration form
Usergroup
10|Vendor
11|End User

I have also another fields called
address,city.

I want to show the address & city field if the the user selects usergroup as vendor. Otherwise hide the field.

I tried to do it using following ways.

1.
In usergroup field
Equal
field : usergroup
custom value : 11
Target action : hide
target field : address,city

Equal
field : usergroup
custom value : 10
Target action : show
target field : address,city

Equal
field : usergroup
custom value :
Target action : hide
target field : address,city

2.
In address field
Equal
field : usergroup
custom value : 10
Target action : show
target field : address

Equal
field : usergroup
custom value : 11
Target action : hide
target field : address

In both case the validation is not working properly on the user registration form.

How to do this? Their might be some JS issues.

Please guide me through this.

Thanks in advance...!!!
