If statement with lookup array... any advice?

[DanH]

I am trying to automate a spreadsheet. The basic formula is this... Any
suggestions or corrections would be appreciated.
=if(Logical_test, lookup_array, lookup_array)

actual formula

=IF(B3="Back
Mount",LOOKUP(B56,{2050,3250,5150,8500,1150,15400,18250,22500,26000,31000,41000},{128,158,188,228,248,278,308,338,368,408,408}),LOOKUP(B56,{3800,5300,6200,8700,13500,17000,21000,26000,33000},{"X12B39",'X15B39","X18B39","X22B39","X24B43","X27B47","X30B55","X33B55","X27B71"}))

I have also tried

=IF(B3="Back
Mount",LOOKUP(B56,{2050,3250,5150,8500,1150,15400,18250,22500,26000,31000,41000},{128,158,188,228,248,278,308,338,368,408,408}),if(b3="Top
Mount",LOOKUP(B56,{3800,5300,6200,8700,13500,17000,21000,26000,33000},{"X12B39",'X15B39","X18B39","X22B39","X24B43","X27B47","X30B55","X33B55","X27B71"}))"")

Thanks.

You had a single quotation (in front of X15B39) in the last half of formula
that was screwing things up.

=IF(B3="Back
Mount",LOOKUP(B56,{2050,3250,5150,8500,1150,15400,18250,22500,26000,31000,41000},{128,158,188,228,248,278,308,338,368,408,408}),LOOKUP(B56,{3800,5300,6200,8700,13500,17000,21000,26000,33000},{"X12B39","X15B39","X18B39","X22B39","X24B43","X27B47","X30B55","X33B55","X27B71"}))

Thanks... I think I've been stairing at the screen for too long. I had two
other people look at this. I had asked them to verify that all my quots were
there and parenthesis were there but nothing. Good eye.

Thanks again.

You could greatly reduce the length of your formula if you were to setup a
lookup table.

With this data in the range D1:E11 -

2050.128
3250.158
5150.188
8500.228
1150.248
15400.278
18250.308
22500.338
26000.368
31000.408
41000.408

With this data in the range G1:H9 -

3800.X12B39
5300.X15B39
6200.X18B39
8700.X22B39
13500.X24B43
17000.X27B47
21000.X30B55
26000.X33B55
33000.X27B71

Then your formula becomes:

=VLOOKUP(B56,IF(B3="Back Mount",D1:E11,G1:H9),2)
