I'm trying to match my selection from a dropdown list to a row, and then my
selection from a different drop down list to the column that matches it, so I
can retrieve the cell that both the column and row match up to... Similiar to
a times table.

My best shot is:

=IF(B4=0,"
",VLOOKUP(B4,FixType!$A$1:$V$58,(HLOOKUP(C4,FixTyp e!$A$1:$V$58,1,FALSE))))

But it only *sometimes* returns a number from the FixType worksheet, and
it's either wrong or #VALUE.

Thanks,
PC
