Question : HLOOKUP newbie question

Hi

I am new to working with HLOOKUP and VLOOKUP and find the examples given within Excel to be rather confusing and cumbersome.  I have a worksheet as follows:

     A     B     C     D     E     F     G     H     I     J     K     L
1                              105 106  107 108  109 110 111 112
2         start  end
3          107                              p
4          110                                                  p
5          108   110                             p           q

There can only be one occurance of a 'p' entered per row.  Once the 'p' is entered, I want a formula in the corresponding B column to display the contents of Row 1 data above the 'p' that has been entered by the user.

What formula can I use to achieve this?  Likewise, if a 'p' is entered in one column, and a 'q' entered further on, can I achieve what is demonstrated in row 5 above (and is it possible to make the rows h5 -> j5 highlighted in a separate colour, if a p and q are entered).

I realise I am asking multiple questions here, but will award the points to anyone who can answer the first and most pressing question.

Answer : HLOOKUP newbie question

try selecting e3:L5 then use this for the Formula Is

=AND(COUNTIF($E3:$L3,"p")=1,COUNTIF($E3:$L3,"q")=1,COLUMN(F3)>=MATCH("p",3:3,0),COLUMN(F3)<=MATCH("q",3:3,0))
