Copy value, not formula, from one cell and paste to another

Hey guys, I have another question and I do believe this one will be VB related,

I will attach what my sheet looks like now:



The red arrows there show the cells I'm trying to work with. Basically, when the button is pressed, all the info in under the "Your Positions" section gets entered and the countdown starts. What I'm having trouble getting to work is this: when the button is pressed, I want the "Start" value to be whatever it shows in cell M6 at the time of the button press. The cell under "Current" shows the live current streaming price. Since I am streaming almost all of these values from an online source, just having the Cell1 = Cell2 kind of setup will not work as they will always change. I just want it to basically copy and paste the value in the cell upon the button press.

I have tried a lot of different kinds of copy and paste options, but the other problem I'm having is that, because these values are being streamed second by second, if the live value cell number changes then the "Start" value will change to. I hope I explained this well enough.

Any help with this will be greatly appreciated! Thanks,
