JavaScript Onload Event count

As a first step see if your code produces any Javascript errors:

http://xlinesoft.com/phprunner/docs/troubleshooting_javascript_errors.htm
If there are no errors you need to set breakpoints and step through the code to see which part of calculation doesn't work.
Here is the article that can help you set breakpoints and step through the code:

https://developer.chrome.com/devtools/docs/javascript-debugging
Also, if you have a valid support contract post your application to Demo Account and open a ticket at http://support.xlinesoft.com sending your Demo Account URL. 'Demo Account' button can be found on the last screen in the program.

thanks You Reply~

1.Use syntax is syntax ok

2.Use Debugging JavaScript ,but Still can not understand, Why did not value?

3.I change Program After that conditions case '+': and case '-': and case '/': and case '': Value calculation is correct

But case '': ctrlempty_timber.setValue and ctrlsolid_wood.setValue Still is null　

Can kindly advice? Thanks.

　case '':

if ((ctrlsymbol.getValue()=null )&& (ctrlbuckle_length.getValue() > 0 ) ) {

　　　　.

.

if ((ctrlsymbol.getValue()=null ) && (ctrlbuckle_length.getValue() =0 ) ) {

I'm not sure what else I can add here. Someone needs to step through this code to find that the issue is. It's not possible to tell what might be wrong with it by just looking at this code.
