Hello and thanks for the post
I have done the same but instead of Due date i have End date.
But after validation i cant leave the field blank. I want End date to be blank so that i can enter the value after task is over.
Will be happy if i get some help from you.
Thanks
Hello Bhat,
In your case you have to check if the field is blank before the validation rule fires. If Empty return true or if value is there then check with validation formula. Following will fit to your case
=IF(ISBLANK(EndDate),TRUE,IF(EndDate>StartDate,TRUE,FALSE))
Happy coding.
Regards,
Adi
=DueDate>StartDate
I used the same string above replacing DueDate with EndDate and SharePoint 2013 returns and error code of this message:
“The formula cannot refer to another column. Check the formula for spelling mistakes or update the formula to reference only this column.”
I want people to only be able to schedule in 15 minute increments.
Trying to validate the minutes in the End Time column.
=INT(([End Time]-[Start Time])*1440)<=15
Help!
