Problem with simple math in auto it

[AcidCorps]

I'm working on getting the progress of an upload to a website, I copy and pasted the string I'm working with:

'00:00:00 (1.43 KB of 10.00 MB)'

and am using that to figure out the code this is what I came up with:

$Base = '00:00:00 (1.43 KB of 10.00 MB)'
$Transfered = StringTrimLeft($Base, StringInStr($Base, '('))
$Transfered = StringLeft($Transfered, StringInStr($Transfered, ' '))
$Total = StringTrimLeft($Base, StringInStr($Base, 'of ')+2)
$Total = stringLeft($Total, StringInStr($Total, ' '))
$Progress = ($Total / $Transfered) * 100
MsgBox(0,'',$Progress)

all its returning is: -1#IND

I also tried to round $Transfered & $Total and it would always return 0, I'm sure it's something stupid, any ideas?

That's a divide by zero error. Your divisor is a string, which evaluates to 0. Try this:

$Transfered = Number($Transfered)
If $Transfered <> = 0 Then
    $Progress = ($Total / $Transfered) * 100
Else
    MsgBox(16, "Error", "Operation not allowed:  Successfull divide by zero would destroy the space-time continuum!")
EndIf

P.S. Number() conversion is required on $Total also, so you could just do:

$Base = '00:00:00 (1.43 KB of 10.00 MB)'
$Transfered = StringTrimLeft($Base, StringInStr($Base, '('))
$Transfered = StringLeft($Transfered, StringInStr($Transfered, ' '))
$Total = StringTrimLeft($Base, StringInStr($Base, 'of ')+2)
$Total = stringLeft($Total, StringInStr($Total, ' '))

$Progress = (Number($Total) / Number($Transfered)) * 100
MsgBox(0,'',$Progress)
