Subform Client Script

Subform Client Script

Good day, 

I have a subform where users can subscribe to various magazines. I would like to prevent the user from selecting the same magazine twice when adding a new row. Is there a way to prevent the user from doing this? (Can it be done via a client script?)

I also have two date fields in the same subform, where the user can select a start date and end date for the subscriptions. How can I alert the user if the start date is after the end date? 

Lastly, I am unable to get the values in a subform when I am using a Client Script. Even though the trigger is set to "onChange" of  a subform field, it does not look like a change is registered...

Any help with subform validations and alerts would be greatly appreciated.

                                                A better clarity so you can create other users to start using Zoho Mail. You can directly Add Users from the Control Panel to your Organization. You can invite users with the existing email address. If the person (user) already uses ZohoCRM, then you can import users from Zoho CRM. You can also import them using a .csv file. (if you are planning to add them in Bulk)  In this topic, We will be discussing on how to Add and Invite users only.  The Import options are self explanatory. ____________________________________________________________________________________________________________
