Custom error conditional logic not working

Hi,

Im trying to use the conditional logic section in contact for 7 redirection to make a field required sometimes, based on the value of another field.

I have set up redirection with condition logic and its works perfectly, and although the custom error works, it ignores the conditional logic and always validates the field regardless of what i enter in the conditional logic section.

My form looks like the below, im trying to get it to only require business-name-pop-up
if the business tab has been picked.

Any help would be appreciated, thanks

<div id=”repair-form” class=”on-pop-up”>
<script>

function setRepairFor(){

var toggle = document.getElementById(‘repair_toggle_pop_up’);
var input = document.getElementsByName(‘repair-for-pop-up’)[0];
var business_input = document.getElementsByName(‘business-name-pop-up’)[0];
var business_postcode = document.getElementsByName(‘business-postcode-pop-up’)[0];
if(input.value == ‘Home’){
toggle.children[0].className = ”;
toggle.children[1].className = ‘on’;
input.value = ‘Business’;
business_input.className = ‘ps-custom-input’;
business_postcode.className = ‘ps-custom-input’;
}else{
toggle.children[0].className = ‘on’;
toggle.children[1].className = ”;
input.value = ‘Home’;
business_input.className = ‘ps-custom-input none’;
business_postcode.className = ‘ps-custom-input none’;
}

}
</script>
