Using "if" in calculated item.

[mhoop]

I have a master/slave server pair that will have a count when either is active. I am capturing the count as ServerA_Count and ServerB_Count. that is working. I want to display only the count on the master server. I have a boolean ServerA_Master/ServerB_Master telling me which is active.

for a calculated item is there a way to do something similar to pseudo code below?

if (ServerA_Master)
then
Display_count = ServerA_Count
else
Display_count = ServerB_Count
endif

thanks
