Running validation before the 'save as' script

Question

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

Answer 1

got it to work: my script was wrong, it now looks like this:
if 
(form1.execValidate()== true){
app.execMenuItem("SaveAs");
