problem deleting entire row based on a condition

[mehdoush]

Hey everyone

I have a problem deleting rows based on a condition, i didn't know how to use offset method.

i'm using a table like this one :

A B C
1 Main design1 FFR0
2 Extra design2 FFR0
3 Main design3 FFR0
4 Extra design4 FFR0
.
.
n Main designn FFR0


I want to delete entire row if "FFR0" in column C exists in a row beginning by "EXTRA" (column A)

thanks in advance for your help
