Very basic Radial Wipe / Opacity expression

Question

Hey GuysSorry for asking what is probably a super elementary question. Why doesn't my simple expression below achieve the result of dropping the opacity by 25 for each quarter of completion? Am I missing something basic? Instead it stays at 100% until the final quater where it drops to 25. Im pretty fresh at expressions so hope sorry if such a function is written wrong.CheersEXPRESSION ON OPACITYtrans=effect("Radial Wipe")("Transition Completion");if (trans<=75 && trans>50){75}if (trans<=50 && trans>25){50}if (trans<=25 && trans>0){25} else {100};

The last if statement always results in 20 or 100. You could write it like this:

trans=effect("Radial Wipe")("Transition Completion");

if (trans<=75 && trans>50){

75

} else if (trans<=50 && trans>25){

50

} else if (trans<=25 && trans>0){

25

} else {

100

};

or you could do something like:

trans=effect("Radial Wipe")("Transition Completion");

if (trans ==0) {

100

} else {

Math.ceil(trans/25) * 25;

}
