[EquisMetaStock Group] Re: LLV: "...must contain only constant data"

["mlaporte99" <mlaporte99@xxxxxxxxx>]

Dusant,

Thanks for your quick reply... and thanks for pointing ValueWhen, 
which I have never heard of before!

Unfortunately, I tried your suggestion and I am still having the 
same issue.

What the LLV complains about is the fact that instead of entering  a 
fixed period, I pass a variable:

LLV(VVP,PerSinceLower) ... in this situation, LLV accepts the VVP 
variable (whih is the result of my formula), but does not accept the 
PerSinceLower (which is a variable containing the amount of periods 
since the stock crossed -1 from above).

Thanks again!
Martin
