A dynamic sum formula - Excel












1















Guys I am trying to write a dynamic sum formula where the array range starts from a cut-off date ( this date changes every month ).



I have the periods in the top first row 201801 in A2, 201802 in B2 etc.
and starting from A3 I have the sales' figures.



e.g. the cut-off date is 201806, so I need my sum formula to be =sum($F3:L3)



what I was trying to do is =sum(ADDRESS(3,MATCH($B$1,$A$2:$L$2,0),3):L3)



ADDRESS(3,MATCH($B$1,$A$2:$L$2,0),3) returns $F3 which does not work in the sum formula!

    You just need and INDIRECT to convert to a range ref =SUM(INDIRECT(ADDRESS(3,MATCH($B$1,$A$2:$L$2,0),3) &":L3")).

INDIRECT is volatile so may not be the best function to use.



I take it that L3 is static, and you're looking to sum from the lookup value to L3.





  • MATCH(201806,$2:$2,0) will return the column number that 201806 first appears in.


  • INDEX($3:$3,,6):$L$3 will return a reference to F$3:$L$3 (F being the sixth column - replace 6 with the MATCH function).


  • SUM(F$3:$L$3) adds it all up. Replace F$3:$L$3 with the INDEX.


The final formula would be: 



=SUM(INDEX($3:$3,,MATCH(201806,$2:$2,0)):$L$3)


Replace 201806 with a range reference.



If the end date is variable you can use another INDEX function to find it.

This finds the last date using the MAX function: 



=SUM(INDEX($3:$3,,MATCH(201806,$2:$2,0)):INDEX($3:$3,,MATCH(MAX($2:$2),$2:$2,0)))


This adds from June to December: 



=SUM(INDEX($3:$3,,MATCH(201806,$2:$2,0)):INDEX($3:$3,,MATCH(201812,$2:$2,0)))

Monofisismo

Image
Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri

Olmecas

Image
Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México
