Try Catch issue

[curtis_fraser]

I have a function that is called and the error messages form the catch work ok, but the reurn fails as there is a java error at the end of the try statement. I know it will be something ovious, but I can not see it. If no error is caught, then there is no error in the try block.

Any help would be appreciated. Thx

The syntax of try{}catch {} is wrong.

it should be
<code>
try {
// But your code
} catch (Exceptionclassname variable) {
//But your errormessage here.
}
</code>

[curtis_fraser]

it is in this format. it is inserted into a document

code
try{}
catch{}
code

It is ok, I've already fixed it. Passed in the name of the form and changed to set focus to field that way if an error occured. Seems to work since focus actually happens.

Thanks anyway.
