I have a photo gear base with all my gear, I have one table with all the gear and i have one table with shoots where I pick out the gear for each shoot.
I would like to add weight (as in kg) field to my gear table in the Shoot table i can have a summarized weight of all the gear for each shoot.
Will this be possible?
Yep, you can have a number field in your Gear table where you enter the weight of an item in kg.
Then in your Shoots table, I presume you have a linked record field where you are linking your Gear for a shoot. In addition to that linked record field, you’ll need a Rollup field that Rolls up:
Linked Record Field: Gear Field to Rollup: Weight Rollup Function: SUM(values)
That Rollup field will give you the total weight of all the Gear you have selected for the Shoot.
