How to make " Add attachments" mandatory and prevent from submission based on Variable selection

[Naresh_5120]

Dear Community,

I need some suggestion to make " Add attachments" mandatory in catalog item and prevent from submission the catalog item form  based on Yes/NO Type Variable selection. If Variable called "do_have_approval" is Yes then make the " Add attachments" mandatory in catalog item and prevent from submission the catalog item form, if attachment is attached then allow to submit the form. 

I am trying to achieve this through catalog client script but its not working.

Hi @Naresh_5120 ,

I tried your problem in my PDI and it works for me please check solution below 

I created 2 variables on my Catalog item 1. Is Approval(Yes/No), 2. Attachment (attachment type)

I created one OnSubmit Client script and add below code 

function onSubmit() {
   //Type appropriate comment here, and begin script below

   var approval = g_form.getValue('is_approval');  // Yes/No variable

    if (approval === 'Yes') {

        var attCount = g_form.getControl('add_here').attachments
            ? g_form.getControl('add_here').attachments.length
            : 0;

        if (attCount === 0) {
            g_form.addErrorMessage("Attachment is required when approval is Yes.");
            return false;  
        }
    }

    return true;
   
}

Result

When I select yes and try to submit it shows me error

Please mark my answer correct and helpful if this works for you

Thanks and Regard,
