Need help with BMI Calc

[TheScriptkiddie]

Hello! My first time on this forum. I'm a newbie when it comes to autoit.

I've been trying to figure out a BMI Calculator. So I have 2 questions.

*First: How do I get a number from GUICtrlCreateInput to another GUICtrlCreateInput?

*Second: How do I calculate this right? (It just says "Result" when I press "Calculate.")

GUICreate("BMI Calculator", 300, 138)
GUICtrlCreateLabel("Length in meter", 8, 8, 100, 20)
GUICtrlCreateLabel("Weight in kilogram", 8, 44, 100, 20)
GUICtrlCreateLabel("Underweight  Ideal       Overweight        Obesity", 8, 72, 300, 20)
GUICtrlCreateLabel("< 19     |   19-25   |   26-30   |   > 30", 8, 88, 300, 20)
GUICtrlCreateLabel("Result", 8, 110, 100, 20)
$insertLength = GUICtrlCreateInput("", 108, 8, 35, 20)
$insertWeight = GUICtrlCreateInput("", 108, 44, 35, 20)
$result = GUICtrlCreateInput("", 108, 110, 35, 20)
$calcBMI = GUICtrlCreateButton("Calculate", 192, 8, 100, 20)
GUISetState(@SW_SHOW)

$math = $insertLength * $insertLength / $insertWeight

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

        Case $calcBMI

            MsgBox(0, "Result", GUICtrlRead($math))

    EndSwitch
WEnd

1. GUICtrlRead($Input1) then GUICtrlSetData($Input2)

2. $math is not a control (that's why you can't get anything read from there) - use: MsgBox(0, "Result", $math)

Not on your dot-point but VITAL for your script: you need to use GUICtrlRead($insertLength) ... on your $math calculus.

Something to NEVER forget: if it is a control handle (e.g. $insertLength = identifier of an Inputbox) you need to use GUICtrlRead if you want to get its value.

I'm sorry but nothing of those answeres are working (sadly)

When I try the GuiCtrlRead($insert1) then GuiCtrlSetData($insert2) it says "ERROR: GUICtrlSetData() [built-in] called with wrong number of args."

When I try the second answere it give me the result of anything and says: "-1.#IND"

You have to assign the GuiCtrlRead($insert1) to a variable and then use the variable in the GuiCtrlSetData($insert2) like so:

$var = GuiCtrlRead($insert1)
GuiCtrlSetData($insert2, $var)

$var = GuiCtrlRead($insert1)
GuiCtrlSetData($insert2, $var)

It works fine when I try out your code. The insert1 goes to insert2.

But when I change it to:

$var = GuiCtrlRead($math)
GuiCtrlSetData($insert2, $var)

Then in insert2 the text "Result" comes. I have no idea what this is :S

I have tried this:

GuiCtrlRead($math)
GuiCtrlSetData(-1, $result)

But then it gives me the result of "11" and not the result I want from:

$math = GuiCtrlRead($insert1)*GuiCtrlRead($insert1)/GuiCtrlRead($insert2)

[TheScriptkiddie]

Sry it chould be this on the math, but still not working for me. It gives me the value: "11"

$math1 = GUICtrlRead($insert1)*GUICtrlRead($insert1)
$math = GUICtrlRead($insert2)/$math1

If I count my BMI that chould be on insert1: 1.76

And for insert2: 69

So: 69/(1.79*1.79)=22

You are trying - again - to "GUICtrlRead" a variable and I told you that it doesn't work. (GuiCtrlRead($math))

This line is wrong:

$math = GuiCtrlRead($insert1)*GuiCtrlRead($insert1)/GuiCtrlRead($insert2)

It should be:

$math = GuiCtrlRead($insert2)/(GuiCtrlRead($insert1)*GuiCtrlRead($insert1))

This works for me!
