Expressions and Defining High/Low Limits

[Roons1159]

I have an accuracy requirement to assign a 1.5% and a 1% High/Low  from a previous test.  The previous test is a Numeric Array where the first 12 values have to be assigned a 1.5% limit and the remaining 4 have a 1% limit.  

Is there a way to do two while loops on the same step or do I have to break out each element in the array and define its own Parameter.

So basically I have something like this so far:

First test with post expression:

Parameters.Test

= Step.NumericArray

Then I have an expression step with the loop options going 1-16 with this... 

RunState

.NextStep.Result.Measurement[ RunState.LoopIndex ].Limits.Low = (Parameters.Test[ RunState.LoopIndex ] * 0.985),

RunState

.NextStep.Result.Measurement[ RunState.LoopIndex ].Limits.High = (Parameter.Test RunState.LoopIndex ] * 1.015)

But as you see that will add a 1.5% to all of them...Do I have to break out each element in the array individually?? Or is there a way to modify that expression to make the last 4 values of my array multiply by .99 and 1.01?

Thanks

I got it.. I didn't know I could define paramters for any given step in a sequence, only thought Step, previous step, and next step...
