Search two different elements from excel

Hi all,

I have an excel file and its consists of Freq, DOA, Voltage-1, 2, 3 & 4.

Freq & DOA are the inputs to find out the voltages. But here one frequency corresponding to set of DOA Values. That means Both the values (Freq & DOA) are repeating in the excel.

For more clarity please find the enclosed excel sheet.

If it is not repeating means we can easily search but here the value are repeating and i am not able to match the both row indexs.

Please provide the solution for this case.

Thanks & Regards,
