This question was asked in the Formidable forms Slack group earlier today and the answer, although simple, is really useful and versatile. The code:
<script type="text/javascript">
$("#field_bttvs").attr("required", false);


var isreq;
var val1 = $("select[name='item_meta[1601]']").val();

if (val1 == 'Yes')
{isreq = true;}
else if (val1 == 'No')
{isreq = false;}
else if (val1 == '')
{isreq = false;}

$("#field_bttvs").attr("required", true);
$("#field_bttvs").attr("required", false);
The snippet above uses a dropdown field and a text field but can be adjusted to use almost any fields. Replace #field_bttvs with the field key for your text field and 1601 with the field ID of your dropdown field.
