double v,hLookUp

Hi,

I have a hunch, a double vlookup is the solution to my problem. But I can't get it to work, cause of the troublesome A, B, columns. They must contain hours and minutes, where A are the hours and B are the minutes. Formating is regardless.

I have this table:

Book1.xlsx

I need to create a function, in a single cell, that will return my exact percentage, from today(), and column A, B. For example, if today is the 17th of May, and the current hour is 14:05, the percentage would be 9%. If it would be 20th of May, and the current hour is 15:45, the percentage would be 14%. Basically, every half and hour, the percentage in the cell should change.

Please help,
Thanks in advance,
Dorian
