Min date doesn't work with Sum

[#1]

Hello All,

I am trying to calculate an indicator using minimum date. So i set a
variable called 'vPeriodStart' like this

vPeriodStart= min(uDAY) and it gives the earliest date back for a selected fiscal period. Now if i want to use this variable like this

sum(if(Opening > $(vPeriodStart)
or ClosingDate
< $(vPeriodStart) ,0,1)) it
does not work. I also tried

sum(if(Opening >min(uDAY) or ClosingDate < min(uDAY),0,1)) but same result it gives me no value back.

i also tried to format date in every
possible way with Date and Date# it does not work. I am confused why i am
unable to use Min(Date) function in sum formula.

now i if set the value of variable

vPeriodStart= today()

vPeriodStart='09.09.2013'

it works

Now i need to make it works with vPeriodStart= min(uDAY) I tried every possible way but it not working. I am wondering if anybody can help me this
