Delay in field calculation appearing

Question

Hi all
Apologies but my coding skills are a bit dated.
I have three fields A,B and C
User puts a number into A and B calculates the value of this multipled by a number using a bit of Javascript
var field2 = this.getField("CPDNo").value;
event.value = field2 * 25;
Now C does some checks on the value of B to determine whether to use a minimum value or a maximum value here
var field1 = this.getField("cpdval").value;
if (field1<"100"){event.value = "100";
} else if (field1>"7500"){event.value = "7500";
} else event.value = field1;
What I find is B is always correctly calculated but C will wait until I click into another field before performing its calculation...
What am I doing wrong here??
thanks
george

If the contents of the field mscval is a number you should not be comparing it to string value.
Are you getting any errors in Acrobat's JavaScript console?
Are you sure your comparisons are in the correct order for what you are trying to accomplish?
I would have coded this as follows:
var field3 = this.getField("mcsval").value;
// default value
event.value = field3;
if (field3 < 100) {
// field3 less than 100
event.value = 100;
} else if (field3 > 7500){
// field2 greater than 7500
event.value = 500;
or
var field3 = this.getField("mcsval").value;
switch(true) {
// field3 is less than 100
case (field3 < 100) :
event.value = 100;
break;
// field3 is greater than > 7500
case (field3 > 7500) :
event.value = 500;
break;
// all other values
default:
event.value = field3;
break;
