Hi,
I'm running an email campaign analysis and need to lookup a date within a date range and then return the earliest value associated to it (otherwise there are multiple values and I get blank values)
Table 1
| Email Campaign | Start Date | End Date |
| A | 14-Oct | 21-Oct |
| B | 15-Oct | 22-Oct |
| C | 26-Oct | 31-Oct |
Table 2
| Order Date |
| 15-Oct |
| 26-Oct |
27-Oct |
Desired Output
| Order Date | Campaign |
| 15-Oct | A |
| 16-Oct | A |
| 27-Oct | C |
This is because 15-Oct falls within two set out date ranges it takes the Campaign with the earlier Start Date.
I've tried using FIRSTNONBLANK but haven't got the desired result.
Any help would be appreciated.
If you unpovited your first table
| Email Campaign | Date | |
| A | start date | 14-Oct |
| A | end date | 21-Oct |
| B | start date | 26-Oct |
etc.
Then you could just get the MIN() start date associated with the campaign
rather than having to do multiple passes seeing which start/end date groups your order date fit into

Thanks sir, so how would the lookup now work if I unpivot the table?
Which formula would I need to use to check if an order falls between the start and end date of a campaign?
