 ### 1: Create Custom Field 
 Create two custom fields in Cisco Vulnerability Management:
-1) Create a *numeric* custom field to populate the exact # of days . This field is named as *vuln_age* in the script 
-2) Create a *String (long)* custom field to populate the range of days . This field is named as *vuln_age_range* in the script

+2) Create a *String (long)* custom field to populate the range of days . This field is named as *vuln_age_range* in the script.
 
 *Note: It is recommended to select faceted search option for second custom field that is the range of days, to see range options under the vulnerability filters. 
 If faceted search is enabled for first custom field then it will be cumbersome to scroll through all the individual vuln ages that show up.*
