# Field Calculation Javascript

Hi,

I am in need of assistance writing a custom calculation script for a field.

My form includes two fields that include a low and a high value, and another field that has a total value. I need a script to show me the variance if the total value falls outside of the low or high. If the total value falls within the range, it should just say \$0.00

Example: Range is \$2,000.00 to \$5,000.00 and the Total is \$5,500.00. I need it to return \$500.00.

Can anyone help me with this?

Thank you in advance!

YOu'll need somehting like this in the calculation field for the variance

var total = this.getField("Total").value

if(total < 2000)

event.value = 2000 - total;

else if (total > 5000)

event.value = total - 5000;

Hi Thom,

Thank you for getting back to me so quickly.

The problem that I have is the Low and High ranges (the 2000 and 5000) are form fields themselves and will vary based on the users entry.

Is the concept similar?

Yes it is, the limit values are acquired and used in exactly the same way as the total
