I would like to use a custom field as a filter, considering that this field is empty or not. So, I'm using the field as a Dependent and the following formula: greaterThan(strlen($last_activity_date_c),0). However, when I hit save, the system says the formula is invalid: strlen: All parameters must be of type 'string'. Any ideas what should I do here?
Thanks
Hi Monique Ribeiro,
Try:
greaterThan(strlen(toString($last_activity_date_c)),0)
The toString() function converts its content to string so it is compatible in the strlen() function.
