Using the AND and OR functions in the same formula

[Guest]

I need to create a formula that says IF LEFT(A1,1)="7" AND LEFT(C1,1)="A" OR
LEFT(C1,1)="T" OR LEFT(C1,1)="G", THEN CONCATENATE(A1,B1,C1)

I don't know if I can use AND and OR in the same formula, or how to string
it all together. Help, please. Thank you.

Try this:

IF(OR(AND(LEFT(A1,1)="7",LEFT(C1,1)="A"),LEFT(C1,1)="T",LEFT(C1,1)="G"),A1&B1&C1,"")

Does that help?

You can use And / Or in the same function but you need to be very careful
with your bracket and such. Try this...

=IF(AND(LEFT(A1,1)="7", OR(LEFT(C1,1)="A",
LEFT(C1,1)="T", LEFT(C1,1)="G")), A1 & B1 & C1, "")

One way that seems to work.

=IF(AND(LEFT(A1,1)="7",OR(LEFT(C1,1)="A",LEFT(C1,1)="T",LEFT(C1,1)="G")),CONCATENATE(A1,B1,C1))

=IF(OR(LEFT(C1,1)="T",LEFT(C1,1)="G",AND(LEFT(A1,1)="7",LEFT(C1,1)="A")),CONCATENATE(A1,B1,C1),"")

All on one line.......watch out for the posting word-wrap

Assuming that you intend AND to take precedence over OR, and that you want
your answer cell to be blank if the condittion isn't met, then try:
=IF(OR(AND(LEFT(A1,1)="7",LEFT(C1,1)="A"),LEFT(C1,1)="T",LEFT(C1,1)="G"),CONCATENATE(A1,B1,C1),"")

Otherwise, shuffle the formula accordingly.

WELL....afer *carefully* re-reading the request...and realizing that my first
post missed the mark.

Here's an option that you could try
=IF(AND(LEFT(A1,1)="7",ISNUMBER(SEARCH(LEFT(C1,1),"ATG"))),A1&B1&C1,"")

Note: Instead of using the CONCATENATE function, you can just link the text
values to be joined by ampersands (&)

Is that something you can work with?
