functions

[eec]

We are doing a simple functions in class and i keep screwing it up.

PrivateSub btncalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btncalc.Click

Dim snglength, sngwidth, sngheight AsSingle

Dim total AsInteger

'declare varialbes

snglength = Val(Txtlength.Text)

sngwidth = Val(Txtwidth.Text)

sngheight = Val(Txtheight.Text)

'assign txtbox values to variables.

lblvolume.Text =





EndSub



PublicFunction calcvolume(ByVal snglength AsSingle, ByVal sngwidth AsSingle, ByVal sngheight AsSingle, ByVal inttotal AsInteger)

Dim total AsInteger

total = Val(snglength * sngwidth * sngheight)

Return total



EndFunction

it may look worse then before i keep changing things to try and get it to work. basiclly i need to know how i call the value the function is holding back up to display in the label. thank you
if you see anything major wrong please let me know too.
