HI - Im using a visualforce page and wrapper classes to create three data tables. Table1 allows you to select a record(s) from a custom object. This then feeds into table 2 which filters based on the records selected in Table 2.   Table 3 is a list of records selected from records checked in Table2.  This table will form the basis of an Insert process into the custom object.

Tables 1 & 2 work fine, however I cannot for the life of me get table to rerender properly. I'm not sure of the problem is in the controller or the visualforce page but I'm suspecting a simple error I'm overlooking somewhere.

Any ideas??

Thanks in advance
