Running validation before the 'save as' script

Hi

I'm looking for a steer on how to run form validation before implementing the 'Save as' script - is this even possible??

Basically I want the save as script to run in the click event of my newly formed save button only if the validation script returns a positive value i.e. all mandatory fields are completed, I've used the script below:

if

(form1.execValidate()== "false")

{

app.execMenuItem("SaveAs");

}

Any chance someone could point me in the right direction or am I barking up the wrong tree?

Thanks
