Making a Chart with VBA

[ryan.fitzpatrick3]

I have 2 charts on sheet1 named (position sheet) they are centered at
the bottom. I have this code inwhich I found here. What I'm trying to
do is 1) create 2 charts one for white flour and the other for wheat
flour 2) they are linked to buttons so when I push the button it puts
the chart on the sheet. 3) I want the same position on the sheet every
time I click the button 4) if I click the button a few times I don't
want the charts to constantly layer on itself, so this is my code. It
works good then when I save it and reenter it gives me a run-time
error 1004 like. Why did it work and now it doesn't work. Can anyone
help me fix this code where if I click this button 1 times or 100
times it'll be the same even if I save and exit and come back in.
