empty fields required

hello, I have a small form with 3 fields (without chapta) and the send button.
I would not be allowed to leave empty spaces or simply with a single field.
I would avoid such problems of bogus emails.
thanks
(I use the latest version of the program for joomla 2.5)

Hi abombazza,

This this FAQ may help

Bob

thank you GreyHead for your help.

i had try the solution in the link but the problem is:
i have 3 fields text and 1 submit button.
I don't want that is possibile to send a message putting a simple "space charachter" on each fileds.
If the fields is empty, i receive an error if i try to push "send button", but not give me a error if i put on each fields an empty space.
In this last case, i receive strange mail but i can't use a chapta because i don't have many space in the page.
U understand me ?

Thank you again

Hi abombazza,

Then you need to add some more specific validation to the form elements to check exactly what you do want to allow. There are some built in to ChronoForms or you can add custom validations of your own.
