nested shortcodes not working

Hello,

Installed the outerbridge nested shortcode plugin but this nested shortcode isn’t working.
My shortcode:
[gd_listings post_type=”gd_place” tags=”[field location_zipcode length=3]“.]

This nested shortcode [field location_zipcode length=3] should be providing the value for the tags.

Parts of the shortcode are being translated but the final output doesn’t use the value for the parameter. Moreover, after translating, the outer shortcode runs, and some of the inner one does too but shows the “] at the end in the html which indicates the processing of the shortcodes is being interrupted.

This behavior is the same as when the “nested shortcodes plugin” was NOT installed.No difference. Using the latest version of WordPress.

Thanks for any assistance you can provide.
