I love Excel. There is so much you can do with it and every time I set out to create a spreadsheet I run into a question, "well, how do I do this?" and almost always there is an answer. This is a total finesse question, but let's see if anybody is up to the task.
I have a formula in a cell that calculates a dilution for a vial of antigen. Basically the number will be somewhere between 10 and 1000 (that's not crucial). I would like the cell to display in the manner we are used to seeing dilutions such as "1:100".
The easy solution:
="1:"&(my formula)
Here is the problems:
#1: When I do this, the formatting forgets that I don't want any decimal places so I wind up with something that looks like this:
1:109.0909090 instead of 1:109
Any way to make the formula lop off the decimals? Oooh, I'm off to explore. I have an idea. Let's see if I get the answer before anybody else.

| I guess you've already right-clicked and changed the number of decimal places in formatting? |

Put 'int' for integer in front of your parenthesis for 'my formula' ie. "1:"&int(my formula)
This should round your number to the nearest integer.
eta: Nope is just lops off everything behind the decimal. Going to see if there is rnd (rounding function) available.

| Yes, rounding works also, the example is this: ="1:"&ROUND(A1,0) |

YES! I found the INT command.
OK, problem #2:
Here was my original formula:
=IF(AND(K13<>"")=TRUE,1/(0.5/(0.3*(100/K13))),"")
Because the cell K13 now equals "1:whatever" the formula screws up. So I thought I'd just put the dilutional formula in the place of "k13" in the formula above giving me this:
=IF(AND(K13<>"")=TRUE,1/(0.5/(0.3*(100/(D12/(SUM(F12:H12)))*6))),"")
However, the value seems all whacked out. It went from 0.5 to 18. I can't quite figure out why.
The sum of F12:h12 should be 1.0 in this example.
Ignore the AND stuff. That's basically for some conditional formatting I'm doing.

| Don't worry. I fixed it with another set of (). That formula is quite ugly and I bet I could clean up the constants... :) |

And which btw I can't call more than 8 If statements in one cell, anyone know how to call more?

Sorry DD I don't think it can be done without writing your own VBA function

I like to play with excel and have a good bit of experience hacking some complicated spreadsheets together.
So even though you already have it figured out, I couldn't resist throwing in my $0.02 worth.
Here is another way using the CONCATENATE function
the Concatenate function allows you to join 2 or more strings together.
The syntax for the Concatenate function is:
Concatenate( text1, text2, ... text_n )
There can be up to 30 strings that are joined together.
=CONCATENATE("1:",INT(A1+B1+C1/A2))
replace the INT(A1+B1+C1/A2) with your function
Here is one of the many references I've found for excel and where I copied the concatenate reference info from //www.techonthenet.com/excel/index.php

CONCATENATE worked for something else I needed it for thanks for that.
