quick question about "if" qualifier:

I'm wanting to include observations in my anova if the variable "trt" is not equal to 1, 5, 7, or 8.   Here's my command:

anova avegsi study / trt|study / tank|trt|study time trt*time if sexnum==1 & ttest<10 & trt!=(1 5 7 8), repeated(time)

It's obviously not working, otherwise I wouldn't be bugging you all.  The problem is that it isn't actually taking these observations out of the analysis.  Could someone show me how to do this correctly?...(trying to learn Stata on the fly).

Thank you!
