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.

Eg.

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 Charulatha
