# Excel Lookup

How can I make this formula, lookup properly.

=IF(OR(BT21={"P","F","I","NC","WF","WP"},SUM(BT21)>0),VLOOKUP(BT21,TABLES!\$A\$2:\$C\$108,2,TRUE),"")

If BT21 is 92.997 it looks up the table with 92, but I need it to round up to 93.00 and look at 93, is there a way to do this in the Formula?

Try changing the TRUE by FALSE on the VLOOKUP function.

You can use the formula ROUNDUP(number, Number of digits)

jppinto, changing the VLOOKUP to false will not work.

ScriptAddict, Where would I put it?

ScriptAddict, I have found the what to do, thank you:

=IF(OR(BT21={"P","F","I","NC","WF","WP"},SUM(BT21)>0),VLOOKUP(ROUNDUP(BT21,2),TABLES!\$A\$2:\$C\$108,2,TRUE),"")

Do you always want to round up? Should 92.001 round up to 93 or down to (2?

Seems odd that you would use a mix of text and numbers, but anyway:

=IF(OR(BT21={"P","F","I","NC","WF","WP"},SUM(BT21)>0),VLOOKUP(IFERROR(VALUE(TEXT(BT21,"0")),BT21),TABLES!\$A\$2:\$C\$108,2,TRUE),"")

I spoke to soon as this will not work either, as it changes the Possible letter grades to #VALUE!, I will have to reopen the Question

To always round up...

=IF(OR(BT21={"P","F","I","NC","WF","WP"},SUM(BT21)>0),VLOOKUP(IFERROR(ROUNDUP(BT21,0),BT21),TABLES!\$A\$2:\$C\$108,2,TRUE),"")

Like Patrick said, I'm not sure it's a great idea to mix text and numbers - perhaps it would be better to have two separate lookup tables (one for text and one for numbers)  and then use a formula like

=VLOOKUP(IFERROR(ROUNDUP(BT21,0),A1),IF(N(BT21),NumTable,LetTable),2)

Actually, thinking about it, it's almost always a bad idea to have letters in a table with a TRUE lookup table as you can get some incorrect results if the wrong letters are input. Change my above suggestion to

=IF(N(BT21),VLOOKUP(ROUNDUP(BT21,0),NumTable,2), VLOOKUP(BT21,LetTable,2,0))

regards, barry

barryhoudini,
I agree that the mixing or Numbers and Letters is not optimum, I will look into a possible change, but this spreadsheet is rahter large already
You also asked this "Do you always want to round up? Should 92.001 round up to 93 or down to (2?"
92.9727272727273 would be 92.97, but a 92.9977272727273 would be 93.00, does that make sense to you?

It's a mangled issue really, the Lookup table use 0-100 numbers for grading so a 92 = B+ or a 93=A-

I think this might round a little more to your liking.
