Need Help with Javascript for Acrobat Pro 9

Question

Hello,
I am creating a PDF form in Adobe Acrobat Profession 9.  Not having a lot of experience with Javascript, I have found this forum very helpful and have used many of the script examples for other issues I have had.  I was hoping someone could help with the following script, I have tried many variations, cannot get it to work.
var ratio = this.getField("ratio").value
var concentration = this.getField("concentration").value
var result = this.getField("result").value
if(ratio.value>=50.00)
{result.value ='PASS';}
if(ratio.value".value>=40.00)
{result.value ='PASS';}
if((concentration.value ==61) && (ratio.value >= 49.25))
{result.value ='PASS';}
if((concentration.value ==61) && (ratio.value >= 39.25))
{result.value ='PASS';}
if((concentration.value ==62) && (ratio.value >= 48.50))
{result.value ='PASS';}
if((concentration.value ==62) && (ratio.value >= 38.50))
{result.value ='PASS';}
else
{result.value = 'FAIL';}
This is just a piece of the code  The concentration values run from 61 through 99 and the ratio value varies for each concentration value, there is a high ratio and a low ratio.  The result of this field with populate the results field with a PASS or FAIL.  This is not working......any help is greatly appreciated!

Thanks George.  I updated the script to:
// Get a reference to the result field
var ratio = this.getField("ratio");
// Get a reference to the result field
var concentration = this.getField("concentration");
// Get a reference to the result field
var result = this.getField("result");
if(ratio.value>=50.00)
{result.value ='PASS';}
if(ratio.value >=40.00)
{result.value ='PASS';}
if((concentration.value ==61) && (ratio.value >= 49.25))
{result.value ='PASS';}
if((concentration.value ==61) && (ratio.value >= 39.25))
{result.value ='PASS';}
if((concentration.value ==62) && (ratio.value >= 48.50))
{result.value ='PASS';}
if((concentration.value ==62) && (ratio.value >= 38.50))
{result.value ='PASS';}
else
{result.value = 'FAIL';}
However, I am still getting a FAIL result even when the ratio is 50.00 or equal to the passable ratio.
