Hi,
I assume you use Visforms 3.4.3, because this is a bug which I fixed in Version 3.5.1
You can either update to the latest Version, which is 3.5.7 or you can make a small fix in the source code of your Visforms installation.
Open the file components\com_visforms\lib\business\multicheckbox.php
find the following code (line 55)
Code:
if (VisformsValidate::validate('max', array('count' => $count, 'maxcount' => $maxcount)) == false)
replace it with
Code:
if (($count > 0) && VisformsValidate::validate('max', array('count' => $count, 'maxcount' => $maxcount)) == false)
find the following code (line 110)
Code:
if (VisformsValidate::validate('min', array('count' => $count, 'mincount' => $mincount)) == false)
replace it with
Code:
if (($count > 0) && VisformsValidate::validate('min', array('count' => $count, 'mincount' => $mincount)) == false)
I think this will fix the problem.
If not, let me know.
Regards,
Aicha
