Multiple Criteria lookup to extract data from a dump - INDEX MATCH????

[Rossovich]

I am attempting to extract data from a dump onto a blank sheet in a workbook, I would like to create a formula that will look at 3 separate reference items, so that it will pull the correct data.
i.e.
it needs to look at date, time and skill.
I have attached my sheet. the formula would need to go in the green box.
It needs to look at the time (Column A), the date which Cell A2 and the skill which is cell CU1
It needs to look at the tab Week 1 and grab the data if there is any, If it does not find any data, I need it to leave the cell blank.

I looked at VLOOKUP, if statements and Index match. I am not overly familiar with index match, but by the looks of it; it may be my solution???

Any help would be greatly appreciated.
