Set Edit box value with null value

Using SUP 2.2.

I have an MBO with a parameter defaulted value is <NULL>.  So if this parameter is left alone, it would bring all the data back without any specific filter.

However, the parameter, as you might guess is coming from a drop down list which has static values.  The MBO works well when the selected value from the list has a specific value.  But I do have an option in the drop down with "All", which I need to some how set the drop down list with <NULL>.  I've tried setting the field with empty quotation marks, with null and even <NULL>.  But no data is returned.  I am positive that the query does work and should have returned data, that I am very sure off.

So my question is, how can I set this drop down box with null value so that the MBO will work?  Thanks.

    Native app or hybrid app? If native, which platform(s)? If hybrid, have you added any custom code to deal with the null value scenario for select/choice/combobox controls?

      😊  thanks David.  I've enclosed the key param in quotes already, that was just a typo above.  In regards to running the hybridapp.html in Chrome, it works up until when it connects through the MBO.  I'll keep chugging away,  I'm sure there's something minor that I am missing.  Thanks.
