some help with math

[longpole001]

thanks art that works well
i used an exiting variable for the temp one

i also did multi if /then statements , which reduced the compile further - those "and " do add up in compile

i have not seen the command ":" to allow you to put on the same line before btw

here what works

cheers

I’m glad if it saved some memory... I made a bigger post but it looks to have disappeared.
