# Nested IF conditions

R

Hi,

I have a column say col A and I want to concatenate this with other 2 columns (say B,C) columns based on below conditions and populate say column D

1) If col B is null and (col C is null OR col C = 'null' (string), then col D = A
2) If col B has an "@" AND col C is not NULL AND col C <> 'null' (string), then Col D = concatenate (A,B,C)
3) If col B does not have an "@" AND col C is not null AND Col C <> 'null' (string), then Col D = concatenate(A,C)

This seems straightforward, but I am working on this for a while and somewhere it keeps breaking. I just need pretty basic approach (nested IF's may be) to accomplish this.
