radio buttons disabled after entry

Hello I am new to Visforms and I think i like it. 

I use it on my new website mondstukken.basensax.nl. for users to order a mouthpiece.

When I use radio buttons like this
Instrument
sopranino
sopraansaxofoon
c-sopraan
altsaxofoon
c-melody
tenorsaxofoon
baritonsaxofoon
bassaxofoon

Each time an form is entered the option that is used in the form is disabled in the next form. When I delete the stored data of the form it is available again. 
How can I make a form where are options remain enabled?

kind regards

 

Hello Johan,

We're glad you like Visforms and thank you for your great feedback.

The behavior you describe is intentional and clearly configured accordingly.
It's one of the many ways to validate user input.
In your case, the following parameter is configured for the radio field:
Field Configuration >> 'Basic Settings' tab >> 'Validation Settings' group >> 'Unique Values ​​Only' = 'Yes'

If you reset this parameter to its default value of 'No', all radio options will be available again for each new form call.

Validation options are described in the documentation.
Supported data validations:

Best regards, Ingmar

Thank you
