If then nested with isblank count blank?

[kmprice710]

I have four columns of pricing data. If columns A, B, C are all blank, then I want to output whatever is in column D. If Columns A & B are blank but something is in C, then I want C. If Columns A & C are blank, but something is in B, then I want B. If Columns B & C are blank but something is in A, then I want A. There's never a case of something being in A & B, A & C or B & C at the same time.

I think I can write this with an IF/THEN using ISBLANK or COUNTBLANK, but how do I nest it?

=INDEX(A1:D1,MATCH(TRUE,A1:D1<>"",0))
Confirm with CTRL-SHIFT-ENTER rather than just Enter and copy down.
