Validation problems using an image

The following validation code works fine, however, I'd like to use an image as my submit button. When I change the button to: <INPUT TYPE=&quot;image&quot; SRC=&quot;images/pic.gif&quot;> the validation code still works, however, it doesn't stop the form from being submitted. I've tried a thousand variations including: Sub myForm_OnSubmit() without success. Any suggestions will be GREATLY appreciated.

<FORM ID=&quot;myForm&quot; METHOD=&quot;POST&quot; ACTION=&quot;somepage.asp&quot;>
<INPUT TYPE=&quot;text&quot; NAME=&quot;field1&quot; SIZE=&quot;30&quot;>
<INPUT TYPE=&quot;button&quot; NAME=&quot;myButton&quot;>
</FORM>

<SCRIPT LANGUAGE=&quot;vbscript&quot;>
Sub myButton_OnClick()
If Len (myForm.field1.value) = 0 Then
Alert &quot;Please enter a value.&quot;
myForm.field1.focus
Exit Sub
End If

Call myForm.submit()
End Sub
</SCRIPT>

Probably better to list the code as it is not working... When my submit type is &quot;button&quot; everything works fine. When my submit type is &quot;image&quot; the alert will still appear if the field is blank, however, once the user clicks OK on the alert, the form gets submitted without giving the user a chance to fix the blank field. Thanks!


<FORM ID=&quot;myForm&quot; METHOD=&quot;POST&quot; ACTION=&quot;somepage.asp&quot;>
<INPUT TYPE=&quot;text&quot; NAME=&quot;field1&quot; SIZE=&quot;30&quot;>
<INPUT TYPE=&quot;image&quot; SRC=&quot;somepic.gif&quot; NAME=&quot;myButton&quot;>
</FORM>

<SCRIPT LANGUAGE=&quot;vbscript&quot;>
Sub myButton_OnClick()
If Len (myForm.field1.value) = 0 Then
Alert &quot;Please enter a value.&quot;
myForm.field1.focus
Exit Sub
End If

Call myForm.submit()
End Sub
</SCRIPT>

somepic.gif isn't being viewed by another app while you're running this are you?

Nope. This form is the first and only place the image is viewed. I do need to make one correction - when an &quot;image&quot; type is used, the vbScript is ignored completely and the form is submitted, blank fields and all. Sorry for the misdirection.

I think I'd start by putting your script block within your <HEAD> tags instead of after your form tags. Then I'd put a message box as the first thing in your OnClick event code.

Oh, also, isn't Alert a JavaScript function or does this also work in VBScript? I always use the MsgBox function.
