Excel 2010 how to write formula

I have seven columns in a spread sheet with values.  I need to add a column and based on what  is the total of those 7 columns do the following in the new column
if <20 enter a 1
if20-249 enter a 2
if 250 or up enter a 3

Can someone tell me how to do this.  I have never used a formula. Thanks.

Would you please attach an example excel file to show what cells are exactly involved ?

something like this should work:

so what this formula is doing (note I used A1 through G1 in the add the sum statement you can change that if your values are in different columns/rows)
1. Start an If statement
2. checks if the value is between 20 and 249 and sets it to "2" if it is
3. checks if the value is less than 20 and if it is then it sets the value to "1"
4. checks if the value is greater than 249 and if so it sets the value to "3"

that is too much of overkill with so many AND and IF.

you can use the best feature of VLOOKUP with approximate match.

see attached. how simple that is .  just with one short formula.  =VLOOKUP(D2,$A$2:$B$4,2,1)   or hard coded table inside vlookup  simple as this =VLOOKUP(D2,{0,1;20,2;250,3},2,1)
