Hi Uday,

Is your requirement to update the date field to today's date when amount is entered or updated?
If yes then you can accomplish this by making the date field a formula field. Select advance formula and say
IF( Amount__c <> 0, TODAY() ,NULL)

This should do the job:) Let me know if this is what you're looking for!!

Hi Uday,

Try the below trigger:

The below trigger checks the two field and throws an error:

trigger TestTrigger on Account (before update)
for(Account a :
if(a.Amount__c != Trigger.oldMap.get( && a.Date__c != TODAY())
a.Date__c.addError('Date is need to be in UptoDate');

Can you please Let me know if it works or not!!!

If it works don't forget to mark this as a best answer!!!
