Help required with INDEX and multiple MATCH function - Excel 2007

[saundersben50]

Hi

I've attached an example spreadsheet for what I'm looking to achieve. I'm attempting to create a formula that will look up the block, row and seat data found on the database tab and match these 3 cells data with the block, row and seat data on the area tabs. If the 3 cells data matches the 3 cells on the data tab, I would like the client name from the database tab to display in the client column in the data tabs.

I think I should be using the INDEX and MATCH functions, but I'm having real problems making them work after brief success early on, I cannot get the cells displaying anything other than errors. Can anyone help?

Thanks
Ben
