How to reference a layer with a certain checkbox effect ticked

How would I go about doing this? I need to take position property from a certain layer with a checkbox effect ticked. But how do I reference this layer?

This is my current solution, surely there is a better option? It's such an awful work around as I have to have the checkbox effect applied to every layer otherwise after effects gives me the error "missing effect":

i = thisComp.layer(index+1).effect("First Word")("Checkbox");
i2 = thisComp.layer(index+2).effect("First Word")("Checkbox");
i3 = thisComp.layer(index+3).effect("First Word")("Checkbox");
i4 = thisComp.layer(index+4).effect("First Word")("Checkbox");
i5 = thisComp.layer(index+5).effect("First Word")("Checkbox");
i6 = thisComp.layer(index+6).effect("First Word")("Checkbox");
i7 = thisComp.layer(index+7).effect("First Word")("Checkbox");
i8 = thisComp.layer(index+8).effect("First Word")("Checkbox");
i9 = thisComp.layer(index+9).effect("First Word")("Checkbox");
i10 = thisComp.layer(index+10).effect("First Word")("Checkbox");
i11 = thisComp.layer(index+11).effect("First Word")("Checkbox");
i12 = thisComp.layer(index+12).effect("First Word")("Checkbox");
i13 = thisComp.layer(index+13).effect("First Word")("Checkbox");
i14 = thisComp.layer(index+14).effect("First Word")("Checkbox");
if (i == 1 ) {1}
else if (i == 1 ) {1}
else if (i2 == 1 ) {2}
else if (i3 == 1 ) {3}
else if (i4 == 1 ) {4}
else if (i5 == 1 ) {5}
else if (i6 == 1 ) {6}
else if (i7 == 1 ) {7}
else if (i8 == 1 ) {8}
else if (i9 == 1 ) {9}
else if (i10 == 1 ) {10}
else if (i11 == 1 ) {11}
else if (i12 == 1 ) {12}
else if (i13 == 1 ) {13}
else if (i14 == 1 ) {14}
else {0}
