LayoutUpgrades 16.0.2

[sally01]

Hi, just trying to do the version upgrade but getting a failed message on a layout. The error log produces this ....

Match: \\.content-area form table\\.checkout tr th:not\\(th\\.change\\) \\{font-size:0\\.9rem;\\}.*color:<actinic:variable name=\"PaletteBG\" \\/>;\\}
Replace: .content-area form table.checkout tr th:not(th.change) {font-size:0.9rem;}
.content-area form table.checkout tr td.cartheading, .content-area form table.checkout-cart tr td.checkout-cartheading {background:<actinic:variable name=\"CheckoutEM\" />; color:<actinic:variable name=\"PaletteBG\" />;}
Result: Failed

I've checked in Responsive CSS and sure enough I can't find a match either. Any ideas please.
