Excel查找具有多个条件的多个值

Question

I have two tables that I need to compare return a true or false value, the challenge is the user ID appears multiple times in both tables which means my VLOOKUP gets stuck at the first value.

Table 1 relates to Messages sent to users

Table 2 relates to Orders made by users

I want to compare the two tables and see if a user has placed an order within 14 days of being sent each message.

I have tried using a Pivot for table 2 with UserID across the top and date down the left, then using Vlookup and Hlookup to return a value for the exact date but I can never get past looking at an exact date or the first value rather than all values.

Since you are just wanting to say "Yes" or "No" that a record exists based on multiple criteria, I think =COUNTIFS() is the way to go. COUNTIFS() lets you make a count of rows that match multiple conditions. – JNevill Mar 15 '16 at 17:33
