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](https://community.glideapps.com/t/how-do-i-create-a-custom-form/25014). Can you describe your use case in a little more detail? ---

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 1. Yes , my first plan is to show before sunmit 2. Another question, example i got 15 kinds of material but each day not all kind of material to deal with . Example 3. 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 ? ---

> [@atiwat\_tangchaiwatta](#): > > Yes , my first plan is to show before sunmit Okay, so my original answer stands. The only way to do that is to use a custom form. > [@atiwat\_tangchaiwatta](#): > > - 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 ? How are you currently recording this? Can you show me what it looks like inside the Glide Data Editor? ---
