Date field comparison

Content

Hi Team,

I have 2 custom date fields named as firstPPMdate_c and Enddate_c. While saving the record with value, the firstPPMdate_c should be earlier or equal to the enddate.But it is not working properly. Below is the validation script I have used. Please let me know if anyone aware of it.

Thanks,
Shaheela
