Adding Months to a Date

The Date formula allows addition but I get errors when I cross months by adding days or when I cross years by adding months. (Haven't tested years with adding days but that also crosses a month so I would get an error anyway.

I need it to act like Excel and actually add a year for each multiple of 12 months in particular. Days is annoying but I can work with that in other ways.

So I created a formula to force this on the frontend.

=DATE(

YEAR([Start Date]@row)+ INT((MONTH([Start Date]@row)+ Duration@row) / 12),

(((MONTH([Start Date]@row)+ Duration@row) / 12) - INT((MONTH([Start Date]@row)+ Duration@row) / 12)) * 12,

DAY([Start Date]@row))

But it is acting weird. There are times it works, I was testing a Start Date of 11/1/2019 and a duration of 4 months. It worked. Make it 5 months, it says "#Invalid Data Type" - but the column is set as a date type. If I break out the parts, I get a variety of errors but sometimes it works. I even get all three to work and when I put it together, it breaks. So I can get the year to say 2020, the month to 4, and day to 1. But paste all those into a date formula in a date column and it gives me the error. A little frustrated.

I suppose I could use Netdays * 30 but I am stuck on this should be so simple and should work. It is the principle of the matter.

Hi, <\/p>

Instead of applying the formula to \"Multiselect Text String\" row, did you tried with \"Multiselect Values\" row?<\/p>

=IF(HAS([Multiselect Values]@row, [Component ID]@row), \"MATCH\", \"NO MATCH\")<\/p>

Thank you,<\/p>"}]}},"status":{"statusID":3,"name":"Accepted","state":"closed","recordType":"discussion","recordSubType":"question"},"bookmarked":false,"unread":false,"category":{"categoryID":322,"name":"Formulas and Functions","url":"https:\/\/community.smartsheet.com\/categories\/formulas-and-functions","allowedDiscussionTypes":[]},"reactions":[{"tagID":3,"urlcode":"Promote","name":"Promote","class":"Positive","hasReacted":false,"reactionValue":5,"count":0},{"tagID":5,"urlcode":"Insightful","name":"Insightful","class":"Positive","hasReacted":false,"reactionValue":1,"count":0},{"tagID":11,"urlcode":"Up","name":"Vote Up","class":"Positive","hasReacted":false,"reactionValue":1,"count":0},{"tagID":13,"urlcode":"Awesome","name":"Awesome","class":"Positive","hasReacted":false,"reactionValue":1,"count":0}],"tags":[]},{"discussionID":109493,"type":"question","name":"I am having trouble using \"And\", \"OR\" & \"Countif(s)\" to build a formula.","excerpt":"Hello, I am attempting to come up with a sheet summary formula that counts cells if they meet at least one of 3 different statuses in the same column, AND also meet one of 5 different statuses in a separate column.

Hi, <\/p>

I hope you're well and safe!<\/p>

Try something like this.<\/p>

=IF([Date Reported]@row <> \"//www.santa-greenland.com/community/discussion/43751/\", IF([Resolution Date]@row = \"//www.santa-greenland.com/community/discussion/43751/\", NETDAYS([Date Reported]@row, TODAY()), NETDAYS([Date Reported]@row, [Resolution Date]@row)))<\/p>

Did that work\/help? <\/p>

I hope that helps!<\/p>

Be safe, and have a fantastic weekend!<\/p>

Best,<\/p>
