COMPLEX INDEX/MATCH arguments issue: Project Updates Tasklist

@Paul Newcome@Paul NewcomeI need your expertise


My manager has tasked me with referencing data from a hierarchy of rows, for multiple columns, but wanting the Parent Row to be updated from the inputs of the data in the CHILDREN rows, which he then is asking for the most recent update of that selected customer. I am needing the PARENT row to update automatically whenever a CHILD row has been updated or added. My thought process has been to use the INDEX/MATCH function to pull the specific return cell I need, but the issue that I cannot wrap my head around is how to pull the MATCH of the most recent update for the modified column and to INDEX the Project Rating Status of that most recently updated CHILD row.

I am having a world of trouble trying to find out the best way to use these nested functions to automate my Parent rows.


If someone could lead me in the right direction?



I have had many variations of this unfinished function to pull a specific input but my data has always read as #UNPARSEABLE.


See below for overly complicated function:

INDEX(CHILDREN([Project Rating Status]1):CHILDREN([Modified]1),MATCH(MAX(COLLECT(CHILDREN([Modified]1), CHILDREN([Project Rating Status]1), @cell <>"")), CHILDREN([Project Rating Status]):CHILDREN([Modified]1),0), CHILDREN([Project Rating Status]1)

Greetings @brownrobe<\/a>,<\/p>

Here is a possible solution for your formula:<\/p>

=IF(NOT(ISBLANK([Recovery Collected Date]@row)), \"Complete\", IF(AND(ISBLANK([Recovery Collected Date]@row), ISBLANK([Anticipated Collection Date]@row)), \"Incomplete\", IF(AND(NOT(ISBLANK([Anticipated Collection Date]@row)), ISBLANK([Recovery Collected Date]@row)), \"Pending\", \"//www.santa-greenland.com/community/discussion/comment/\")))<\/p>

Please confirm I have your column names correct and adjust as needed.<\/p>

I hope this helps, and have a great weekend.<\/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":[]}],"initialPaging":{"nextURL":"https:\/\/community.smartsheet.com\/api\/v2\/discussions?page=2&categoryID=322&includeChildCategories=1&type%5B0%5D=Question&excludeHiddenCategories=1&sort=-hot&limit=3&expand%5B0%5D=all&expand%5B1%5D=-body&expand%5B2%5D=insertUser&expand%5B3%5D=lastUser&status=accepted","prevURL":null,"currentPage":1,"total":10000,"limit":3},"title":"Trending in Formulas and Functions ","subtitle":null,"description":null,"noCheckboxes":true,"containerOptions":[],"discussionOptions":[]}">
