Compare date variable in script

[saikripa]

Hello,

I have 4 date variables , iDate, hdate, pDate and paDate. I need to check if all the dates are same. 

My code was:

if $(hDate)=$(iDate) and $(iDate)=$(pDate) and $(pDate)=$(paDate) and $(paDate)=$(hDate) then
Let vFlag=0;
else
Let vFlag=1;

This doesn't seem to work.

=if((v1=v2 and v1=v3 and v1=v4 and v2=v3 and v2=v4 and v3=v4 ),1,0)
