passing a result to a txt box deoending on drop down menus

[stan8450]

I am trying to pass a value of 600 into a txtbox (Approximate_fee) when sizeindex < &quot;600&quot; and typeindex==4 and ageindex==1.
this is what I have so far:

var typeindex=document.for[0].Inspection_Type.selectedIndex;
var ageindex=document.forms[0].House_Age.selectedIndex;
var sizeindex=document.forms[0].House_Sqft.value;
if (sizeindex < &quot;600&quot; && typeindex==4 && ageindex==1)
{
document.forms[0].Approximate_Fee.value=&quot;600&quot;;
}


any help appreciated

Does this work?
if ((sizeindex < 600) && (typeindex==4) && (ageindex==1)){
document.forms[0].Approximate_Fee.value=&quot;600&quot;;
}
Also, do you want this?
var typeindex=document.for[0].Inspection_Type.selectedIndex;
or
var typeindex=document.forms[0].Inspection_Type.selectedIndex;
