The link cited doesn't include the mech option for the sheet. The biggest non-obvious aspects of the sheet are that skills are ranks, not bonuses. And to enter 'Low/Medium/High' + 'Letter for Dmg type' in the Damage entry. So a Frost Rifle should have Weapon: Frost Rifle Level: <as appropriate to your mech (e.g., 7)> Range: 150 Slot: 1 (Frame) Special: Automatic Damage: High C Critical: Staggered Cost: <as appropriate (e.g., 28 for L7)> And 'Enhanced Shields' seems to be broken. Or I have yet to figure out how to get it to work properly. I've had to manually adjust the shield points on the attributes tab to get it to work. If you have more specific questions, feel free to DM me
