Findest the lowest occurence in a row

[mrchoppychops]

Hi All

What is the formula I would need to use in the attached spreadsheet to calculated the lowest or first occurrence within a row?

As you can see in the top table Product A is delivered in weeks 2, 4 and 6, what I need is the lower table to show the first week i.e. wk 2 that the product has been delivered.

Is this possible?

Thanks in advance!
