blnNumber = isNumeric(intsalary)
if (blnNumber = false) then
window.alert("Please enter a value")
else
intgross = (52 * intsalary)
if intsalary<6001 then
intrate="0"

inttotaltax = (intsalary * intrate)
document.frmtax.txttotaltax.value = FormatCurrency(inttotaltax,2)

Same answer to your other thread. What's the error? We can read your script, just don't like to do so without you properly described what the problem is.

this one isnt really doing anything, theres an error saying expected if line 34 which is the end function

thanks again

remove spcaes in else if
Should look like elseif

Or do a Select Case statement.

'At present you don't want to submit, you've not proper action
'in case at later time you want to submit with proper action, take this out
window.event.returnvalue=false

if it is taken out, it looks like it does the calculation, displays it and clears the form in a matter of a second, but then if you press back the calculation is displayed.

can someone plese explain this statement, thanks again

ok another question, just realise something while testing, that the user is meant to be entering there weekly salary and not a yearly salary. When i enter a weekly salary it doesnt display the correct net income due to it not calculating the tax. Can anyone tell me why and how to fix this? Thanks!

Biz logic is what you have to figure out yourself, otherwise how do you come up with the script?

>[tt]intgross = (52 * intsalary)[/tt]
It seems intgross is the yearly salary. So the interest rate if-elseif-end if part, should you not change intsalary to intgross, like this.
[tt] if int[red]gross[/red]<6001 then intrate="0"[/tt]
etc etc... The rest you have to figure out yourself following the same reasoning.

One more hint is that intrate is annual rate for 360-day year. When you calculate the inttotaltax, either you meant total annual tax, in that case, it is:
[tt]inttotaltax = (int[red]gross[/red] * intrate) [/tt]
or total 7-day tax which would be:
[tt]inttotaltax = (intsalary * intrate[red]/52[/red]) [/tt]
without taking into account compound rate/present value... You check the overall correctness of the logic.

By 360-day year, I meant 364-day year. If not, you have to adjust again for the slight difference to 365-whatever-day year.
