I’ve spent literally months learning Bubble and creating an app which I was really pleased with. Until today. I just want a basic, fundamental calculation but It seems that Bubble simply doesn’t have functionality that enables someone as apparently thick as me to do it. I’m trying to create a ki…

@joefarrowsmith My apologies to all that I have not read the entire thread in detail, but I did scan through it. :grimacing: Perhaps something along these lines could help a bit. Notwithstanding the current UI, current flows and current dB structure and exact names of the objects … the following a…

Thanks for your reply. Could you expand on what you mean by “Doing the math in the database”?

The problem is to show the total when you load the data in the first place or to show it changing while you change the amount of each item in the RG? Or both :sweat_smile:?

It’s to show it changing while you change the amount of each item. Although I can’t even find a way of doing the calculation… Really appreciate any help. I’m just mocking up a simple example that I can link to here. Will hopefully be back with it very soon.

Honestly the simplest way I’ve found is to use a plugin and I can suggest the “ Repeating Group Tools ” by BDK. This lets you send data from an RG cell to a “receiver” outside the RG then you can run your totals This do not involve interacting with the database, so it’s quicker. That’s the hack-free…

That sounds excellent. Thank you. I’ll look into both of those - I’m in awe of you creating one yourself. Thanks again.

@joefarrowsmith hey I just created this. Enter numbers in Input 1 and Input 2 and it displays the multiplication right next to it. Is this something you’re looking for? - https://mafiamap.bubbleapps.io/version-test/calculation?debug_mode=true

I guess there’s more to it because of the currency format?

@bestbubbledev He needs to extract the total from a repeating group. @joefarrowsmith perhaps hold off using the Communicator plugin - I’ll put a demo together this eve to make sure it solves your use case before you sub/purchase.

[image] robhblake: the “ Communicator ” plugin by SuperStack (i.e. yours truly!). With this you can trigger a workflow that will update your grand total each time the input is updated. I can guide you how to use it if any questions. And why he needs a plugin to do it? It is not easyer to trigg…

Good point :joy: I had mixed up the facts: you can access workflows from within the RG, but you can’t access RG elements from outside the RG (that’s what the plugin solves). My bad - I’ve removed that suggestion. RE the “seach for” solution, I’m not a fan since he will also need a way of tracking t…
