How can I make a customization field mandatory before adding a product to cart?

Hi,

I have a text field where shoppers enter characters for customization product. Currently they can add to cart after selecting the product without filling the field. I want shoppers add the product to cart only after filling the field.

my code is

{% if product.title contains 'Num %}

Enter Plate Number (Max 5 Digits)

abel for=“monogram”>Enter Code

.ep_inline_block {display:inline-block;vertical-align:middle;margin-left:10px;} .ep_block {display:block;margin-top:10px;margin-bottom:2px;}

{% endif %}
