Problem - countConditional not returning related module drop down field count in Calculated Field

Hello All,

I am quite new to SugarCRM. We have recently implemented Sugar Sell on Cloud. I have an ''Opportunity Module" which is related "Meeting" module in a 1-to-M relationship. I am trying to create a Calculated field on "Opportunity" module that will count meetings conducted based on "Meeting Type" which is a drop down field in "Meeting" module.

I am using the following formula:  countConditional($meetings,"type",createList("Client","Triparty")).

However, if I use formula like Count($meetings), this seems to work. What would need to be changed in the formula above?

Thanks - AP
