Hello friends, I am new in the use of Glide.  
I wanted to know if there is a possibility to be able to show the result of an operation I have performed in the upload form.  
That is to say to show the result before sending.  
This operation takes two parameters that are in the upload form, but only performs the operation when the submit action has been performed.

I am thinking of using JavaScript, and implementing Jquery to manipulate the Frond.

Thank you very much.

Like you mentioned, computed columns will not calculate until the form is submitted. I think you would have to create a custom form to get what you want.

This is a simple concept app (copyable), that demonstrates the following techniques: Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide) Preventing duplicate new entries using [User Specific Columns](https://docs.glideapps.com/all/reference/data-editor/user-specific-columns) and [Relations](https://docs.glideapps.com/all/reference/data-editor/computed-columns/relation-column) Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…
