[FONT=&quot]Let me know if you would rather me upload the excel file, but i'd be very grateful if anyone can help me with the formulas. These are the only 2 tasks from a list of 20 and I've been struggling quite a bit to solve them.[/FONT]
[FONT=&quot]Thank you![/FONT]

it looks like it's coursework or some sort and very simple.
the only way to learn is to the research and learn by trying yourself

[FONT=&quot]It's not homework. My father and I started some personal development program and it had multiple tasks to solve. We're doing it together in order to develop multiple skills and learn new things. We tried with MATCH and IF, but on the first task the issue is that we couldn't find ONE formula to detect all duplicates, and for the 2nd task we used <code class="s1wjcqzz-7 kYgbJw" style="margin: 0px 2px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-stretch: inherit; font-size: 13px; line-height: 20px; font-family: "Noto Mono", Menlo, Monaco, Consolas, monospace; vertical-align: baseline; background: rgba(238, 238, 238, 0.8); color: rgb(255, 0, 109); max-width: 100%; overflow: auto;">=IF(C2="FHA",C4*0.0175)</code> , however not sure how to do the IF C2 does not equal FHA, result is 0.[/FONT]

[FONT=&quot]Would still appreciate any help [/FONT]

ok

for the first question you can use a countif() to search within a range, if the result is 2 or greater you got duplicates.

for the second question, e.g. E3 can be =if(C2="FHA", C4*1.0175, 0)
similar for the others

Hey!

Thank you. Still didn't understand completely how to use countif for the first task. I guess it should start like: =COUNTIF(B2:B17), however didn't really get how in the next column should be copied the duplicate values. Maybe I missed something?

And for the second,:
Question 1

=IF(C2="FHA", C4*0.0175, 0)

Question 2

=IF(C2="FHA", C4*1.0175, C4)

Question 3

=IF(C2="FHA", C3*0.78, 0)

Hope this is correct. Appreciate your help, really. Also understood the logic o =IF so that's awesome!
