Thanks a lot. I already got suggestion of parseInt on another forum, I coded the script, but the little complication is what I'm calling page from ActiveVFP (by Claude Fox).

I'm not yet sure how can I debug it.

This is my whole script for the page now: (stored in a table):

Can not post - UT errors out
where ValidateNumber is

/ *ValidateNumber
  This functions accepts a number string and checks if it's a positive integer.
	
	
	Parameters:
		tcNumber			- The number string you want to verify
		toControl			- The control object that is assosiated with the number
		tcUserMsg			- Massage to display if validation fails. Leave blank if you don't want to notify the user.
		tlStayOnF			- Stay (don't loose focus) on control if validation fails
		tlAllowBlank		-	Allow blank tcNumber passed
		tlBlankOnF		- Blank control value if validation fails
		
	Return:						true or false

function ValidateNumber (tcNumber,toControl,tcUserMsg,tlStayOnF,tlAllowBlank,tlBlankOnF)
{
	focusField=toControl; // Global variable to fix a bug with focus in Firefox when called after an alert.

	if (tlAllowBlank && tcNumber.length==0)
	{
		return true
	}	
	
	
	if (tcUserMsg == 'default')
	{
		tcUserMsg = 'Invalid Input. Please enter valid number';
	}
	
	
	 if(parseInt(tcNumber) > 0)
		return true
         else
	{
	 	if (!(toControl==undefined || toControl=='') && tlBlankOnF){toControl.value = "0"}
		if (!(tcUserMsg==undefined || tcUserMsg=='')){alert(tcUserMsg)}
		if (!(toControl==undefined || toControl=='') && tlStayOnF){setTimeout("focusField.focus();",1);}
		return false
	}

}

Do you see something wrong here?

Thanks.
