19BII Program ---> need help!

[Aconzio]

Hallo everybody!

This is amazing...thank you so much for your support..
Still be patient with me as as said I'm not a programmer ..
I only know that all values should be entered without spaces!! That's all!
..and ...I'm using a forum for the very first time!...;-))

For Gene:
I cannot value where the "if, then" logic syntax starts or ends...I'v tried to
catch a photo...hopefully you can see even the cursor blinking on the semicolon!!

For Gerson

so you suggest to change all ".5" into "INV(2)"?--I'll try...

REgards and thanks!!
