    Hi jackj,

    See the measure below, should do the trick

    Purchase Customer Next week = 
    var prior_cust_ids = CALCULATETABLE(VALUES(Cohort[Customer ID]), TOPN(1, FILTER(all('Cohort'), 'Cohort'[Customer ID] in FILTER(all(Cohort[Customer ID]), 
            'Cohort'[Week Ending]  > SELECTEDVALUE(Cohort[Week Ending]))), Cohort[Week Ending], ASC))
    return 
    CALCULATE(DISTINCTCOUNT(Cohort[Customer ID]), 'Cohort'[Customer ID] in prior_cust_ids)​

Prior Purchase Customer Last week = 
    var prior_cust_ids = CALCULATETABLE(VALUES(Cohort[Customer ID]), TOPN(1, FILTER(all('Cohort'), 'Cohort'[Customer ID] in FILTER(all(Cohort[Customer ID]), 
            'Cohort'[Week Ending]  < SELECTEDVALUE(Cohort[Week Ending]))), Cohort[Week Ending], DESC))

Perfect!  This gives me the numbers I need.  One final, final question - thank you again for all this help!  How can I show a list of the Customer Id's that meet these criteria - those who visited the following week and those who did not?  Really struggling to wrap my head around all of this and it is so much easier in Excel.  Thanks so much for all of your assistance here.
