How to add specific values in my Query

Hi all,

I am using this Query in SSMS. I get a "Syntax Error" when I execute it.

My Query is listed below:

SELECT c.* FROM LogisticsPostalAddress a JOIN LogisticsLocation b ON a.LOCATION = b.PARENTLOCATION JOIN LOGISTICSELECTRONICADDRESS c ON b.recid = c.LOCATION WHERE a.RECID = PurchTable.DeliveryPostalAddress value; 

What should I enter in values? Where can I find it?
