Line 2 of code is the only one that works

Question

Line 4 of this code won't work but there is no error code. It's a building permit application form. If the applicant chooses any category but New Residential from ConstructionType dropdown the minimum fee is 60 for a deck under 401 sq. ft. & .15 x value of Deck text field for a deck >=401. These work. If New Residential is chosen the fee is strictly .15 x value of Deck field. This is the part that doesn't work. Here is the code.

var nDeck = this.getField("Deck").value;
if( (nDeck >0 ) && ( nDeck <= 400) ) event.value = 60 ;
else if(nDeck >= 401 ) event.value = nDeck *0.15 ;
else if ( ConstructionType = "New Residential" ) event.value = nDeck *0.15;
else event.value = 0 ;

Answer 1

Mmmh, at least ConstructionType = "New Residential" must be ConstructionType == "New Residential"
