I'm making a sorry excuse for a trainer and it's going all right.
I came across one of those values that change every time and need the nopping stuff done. I have found it in the memory viewer but what do I need to do to get something from it in the cheat table and make a trainer out of it? I want to be able to nop the address in a trainer. Thanks

Use a timer to write in the interval you want, the value you want.

Or... find what writes that address, and then, write those bytes with 0x90

In the memory viewer, actually the disassembler you probably found a line like:
MyGame.exe+123 8948 04 MOV [EAX+4],ECX
and clicked on "replace with code that does nothing".
To turn this into a cheat entry, go to memory viewer->tools->auto assemble, paste, and adapt this:

Thanks Gniarf!
