Hello, i'my trying to compare efficiency of real-time project durations to theoric template durations. 

Projects are linked to tasks and tasks templates ;

-> total duration of a project = sum of the duration of each task

-> duration objective (efficiency) of a project = sum of the task duration objectives

In each project, Im trying to lookup the tasks theoric duration and sum it up to compare it to the actual project duration. 

I'm doing this this way : 
- I link projects to tasks

- Each task is linked to a ''task template''

- I look up the ''theoric duration'' of each task and Sum it up in rollup

The problem is that the sumup calculation is incorrect : see screenshot ->

- the first row, lookup values for theoric durations per project are as follow : 10, 10, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8

=> And the calculated Sum is 20...

Does anyone encounters problem with this kind of sumup ?

Thanks for your help

What field type are you using for your durations? Duration? Number? Text?

Hello, thanks very much for your time and help. It's a lookup field that looks up a number field.

Hello !

No its not the case, the result is the same with a formula SUM field. any other idea ?

Did you try using a rollup field on your project records to look at the numbers in your rollup field on your tasks records? That should work. 

Hello, not sure if i understood correctly, see screenshot of the rollup formatting : 

- Table projects (Routes) : rollup of the lookup fields of field ''objectifs temps' in table tasks (visits)

- Table tasks (visits) : lookup from a linked field (order_ID) to get the ''objectif temps''

"Objectif temps(min)/adresse" is a string, which may be the reason why the total fails.
If it is a number, it will be displayed on the right side of the cell.

How about changing the Lookup field to a rollup field and using the formula Value(values) to convert the values to a number field?

Try using a rollup instead of a lookup in your table tasks.
