Search Client Custom Field set up as date with greater than or less than operators?

[scott_see]

I set up a tickbox Client Custom Field called "Needs work done" and I can pull those up by searching for "on." That's fanatastic. Now I can use WHMCS as a CRM. Sort of.

 

I tried adding another Client Custom Field called "Date of last contact" and entered a value that would sort by date, numerically, and alphabetically -- 201310 Year and month is all I need.

 

I'd like to be able to search for values greater or less than these date values. But it's not working. Is there a way to do this. Or is the client search only an exact match?

 

By the way, the CRM add on is worthless since it only handles prospects and not existing clients, if I'm understanding it correctly.

 

Thanks,

 

Scott
