Syntax Regarding Form Validation Script?

problem is: I decided to apply some client side validation of the site's forms. The following script will probably trigger some indignation amongst you, but this is my first script, practically copy-pasted from snippets I found on the web.The first few lines of the script is the beginning of the validation function, interrupted by the definition of an alert customizing function. My first question is exactly about the place: did I well place this customizing thing, or could you suggest me a better way to place it?After this definition within a definition, the validation script continues and calls/defines many times the removeCustomAlert function. That's because of my second problem: originally, without the alert-customizing function, after the standard alert box had been closed, the related form field got focused.

But the custom function stopped working after that the customized alert box had been applied, so finally I replaced the focus() function, right inside the removeCustomAlert function. That was the only way I could solve the issue, but gosh, it's many many code. So my second question is: do you know an easier way to code this whole stuff?So, the code is:

function checkForm() {
var cname, cemail, cfname, cfemail, cmessage;
with(window.document.frdForm)

[code]....
