LOL children? Look at your spelling and grammar kiddo.
But yes I do have advice for you: learn how to calculate compression ratio for yourself. It only involves very simple algebra and will help you learn the concept much better as well as to understand what changes to the engine affects it.
What "error" are you getting? I put in the numbers myself and didn't get an error. There is a little "warning" box that pops up to tell you that your piston is above the deck surface, but no "error" message.

this calculation is simple its the total volume of the cyl when the piston is at bottom dead center vs the volume when it it at the top. Start by calculation what the volume of the cyl itself is. Basically just (pi*r^2)*h so (3.14*(3.905/2)^2)*3.622 you will subtract that from total volume which is that number, plus the volume IN CUBIC INCHES NOT CC's of the headgasket and the piston dish and the cylinder head, note also that one inch=2.54 cm. If you need cubic inches you have to cube that converison factor so...1in^3=16.378cm^3.

There is a risk in any engine, yours included. The warning on the website is simply saying that your piston will come above the deck at TDC so you need to make a headgasket choice accordingly. Stock GM MLS gaskets are typically .052" thick so the piston can come up about .010-.015" before you will run into trouble.
