Error EMBEDDED [VIEW] Selection: Opens Directory listing

Hi, need your help urgently on Embedded Views

I retrieve a value on a text field [that i use as my search string] to dynamically feed the SHOW SINGLE CATEGORY option. After accepting a value in the text box, the Directory Listing dialog box opens up with a list of names equal to the search string.

How do i prevent opening of the Directory listing?

PLEASE HELP. Thank you in advance

Isaac
