Dear Dr Charulatha 

To get the difference in days, please try inserting the following command in the block of vo3 in your chk file (vo3 must be in ##.# format, vo2 and vo1 must be in <dd/mm/yyyy> format) : 

let vo3=(vo2-vo1) 

I hope it will be helpful. 

Kind regards 

Dr Andriamahenina R.

I need help in writing the command for the following function. 

1 have 2 date fields. the difference between the dates can be less than 30 
days also in some cases. How can I auto calculate the difference in days 
between the 2 dates. 


v01 11/11/2013 

v02 20/11/2013 

I want v03 to be automatically calculated as a difference between the 2 
above dates. 

Many thanks
