I am trying to use Math Column to be simple calculator for my worker , I can’t call it in my Form Screen . I already made Math column in my sheet , please help

Are you wanting to use form values in a calculation and display the results *before* the form is submitted?

That is not possible, because form values are not written to the underlying table until *after* the form is submitted.

To do this, you would need to use a custom form.

Can you describe your use case in a little more detail?

Thanks for your reply , my case is I trying to create form that my worker to submit total amount of arrival materials

Example

- Material A , one box contains of 50 pcs( a) , and there will be some remaining (b )

So my Math column 2 is (50*a) + b

There are about 5 Material so i trying to make 5 Math columns

The important question is - do you actually need the results of the math columns *before* the form is submitted, or can you just apply the calculations to the submitted data and use it afterwards?

Oh , sorry for misunderstanding

- Yes , my first plan is to show before sunmit
- Another question, example i got 15 kinds of material but each day not all kind of material to deal with .

Example - Today only 7 kinds of material come , after submitting form I want table only the 7 material ( any material that value is not zero) if it possible to make table like that ?

Okay, so my original answer stands. The only way to do that is to use a custom form.

How are you currently recording this?

Can you show me what it looks like inside the Glide Data Editor?
