contentToLocal x and y, retreive y only?

hi, i have objects in a group and am using content to local to get the x and y values

however, i only want to retrieve the y value in an if statement but as content to local requires me to enter both x and y its causing issues,

is there a better way to pull the current local coordinates of an objects y value that is in a group or a certain way of getting only the y value using content to local?

im using content to local in an if statement and its always comparing the x value rather than the y as i cant simply enter the y, unless i can???

thanks.
