Why ?

$1 = ""
$2 = 0
if $1 = $2 Then
    MsgBox(0,"","1 "&$1 &" 2 "&$2)
Else
    MsgBox(0,"","work ?")
EndIf

"" equals the Boolean False.

A value 0 will be equal to Boolean false.

Any other number value will be equal to Boolean true.

So use this to make it work

$1 = ""
$2 = 0
if $1 == $2 Then
    MsgBox(0,"","1 "&$1 &" 2 "&$2)
Else
    MsgBox(0,"","work ?")
EndIf

== means tests if two values are equal (case sensitive if used with strings).

Why ?

$1 = ""
$2 = 0
if $1 = $2 Then
    MsgBox(0,"","1 "&$1 &" 2 "&$2)
Else
    MsgBox(0,"","work ?")
EndIf

Because they are essentially equal. If you change the conditional to

if $1 == $2 Then

you will get different results because they are not exactly equal.

It can be even more surprising. Try this:

$1 = "zero"
$2 = 0
if $1 = $2 Then
    MsgBox(0,"","1 "&$1 &" 2 "&$2)
Else
    MsgBox(0,"","work ?")
EndIf

Conclusion: never play with mixing numbers and string in conditionnals. That may hurt!
