# Any way to get around "value must be a constant"?

I am trying to find the low for a period after my open position. I thought I found a way then I realized that the lowest command requires a constant for the time period. Here's my code:
Code:
``````def Entry = if isNaN(EntryPrice()) then Entry[1] else EntryPrice();

def EntryBar = if Entry != Entry[1] then barNumber() else EntryBar[1];

def count = barNumber() - EntryBar;

addLabel(1, "Bars Since Entry = " + count, color.white);

def LL = Lowest(low, count)``````
It tells me the length in the Lowest() must be a constant. Is there anyway to get this to work so that it scans a different length of time everytime?

see if this will give you the low you want.

Code:
``````def Entry = if isNaN(EntryPrice()) then Entry[1] else EntryPrice();
def EntryBar...``````
@Enoch_Bets Unfortunately not... When it states constant it means just that, a constant and NOT a variable... Just one frustrating limitation of Thinkscript...

That worked!
