Pasting into cells that require a double click for each cell?

Assumptions are the reason many things go wrong. YOU don't even know what you're working with, Oracle can look like Excel and statistical tools can look like Excel, even Google Sheets looks like Excel.
What do you want, guessing/ Assumptions, beat at the wrong bush.
Re-read your post and think, would others understand what I am asking?
Maybe, when you have it clear with what you're working with then somebody might be able to give you answer that you could maybe use and do something with.

How can I help with something you don’t even know what you’re using or doing
Imagine I phone the doctor and it hurts when I press here what is it doctor? But he can’t see mee and I don’t tell him where I am pressing .
Sorry guessing and assumptions are not my way to analyse issues

This is clearly not an Excel issue, so I am moving the thread to the appropriate section.

Based on the information given I doubt anyone will be able to help. You can’t advise how to use software when you don’t even know what the software is. You need to find out at work what it is you are using - somebody must know!
