Hi. I'm using OpenOffice.org 2.3 on Ubuntu 7.10. I've got a question about VLOOKUP in Calc. I'm trying to get it to work with letter grades (I'm calculating my GPA), but I've run into trouble. Let's say I have two tables:
In the first table, the columns are: Course, Credits, Grade, and Quality Points. The "!!!" in the Quality Points cell represents what I'm trying to create the VLOOKUP for. In the second table I basically have the numerical equivalents for the letter grades. The idea is I input the letter grades in the first table, and calculations are done (for the quality points) using the number equivalent in the second table.
Basically, I want to VLOOKUP A3 (from the first table) in the second table, and get the value of the second cell, so that I can multiply it by A2 (first table) to get the quality points (quality points is equal to grade times credits). I'm using something like this in A4 (!!!):
The problem seems to be with the plus sign (+) or something (I think). The VLOOKUP returns the value of "A", which is 4.00, instead of the value of "A+" (4.33). If I use an "A-" it works fine, returning a 3.67.
What is going on here? It's been a while since I've used a spreadsheet so I'm pretty rusty. I know I could get this to work by using percentages, but I'd really like to stick to letter grades. Any help would be greatly appreciated.
