Place your cursor over Reference Data and left click on the sub-option Agencies.
To navigate between pages of the table you can either
use the 
button or use the drop down list 
to choose the page you would like to view.
Find the agency that you would like to delete and
left click on the Delete button 
on that line.
A dialog box will appear for you to choose either
to delete the record
or 
to
not delete.
If the item you are trying to delete is associated with any of the data in the database IQSweb will not allow you to delete the data.
