# Re: st: Cond() and if - Help

It would be good see how you used -cond()-.

I believe this one-line statement would work:

replace var1 = cond(var2<= var3 & var4 ==1 & var5 == `i', 0 , ///
cond(var3>var2& var2<= X & var4 ==1 & var5 == `i', 1, ///
cond(var3 > X & var4 ==1 & var5 == `i', 2,var1)))

Or:

replace var1 = cond(var2<= var3 ', 0 , ///
cond(var3>var2& var2<= X , 1, ///
cond(var3 > X , 2,var1))) ///
if & var4 ==1 & var5 == `i'

However, it might easier to read the do-file with multiple -replace- statements.
