dim playerX as boolean
dim Playerturn as boolean
...
...
...
if(playerX = true) & (playerturn = true) then
button1.text = "X"
elseif (PlayerX = false) & (Playerturn = true) then
button1.text = "O"
Else
button1.text = "err"

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

Let me say arg!

& is a string append in vb.net !

USE And (or AndAlso, Or, OrElse!)

Yeah, the clue was "FalseFalse" in the second line of that looooooooong error message.

[wossname]

dim playerX as boolean
dim Playerturn as boolean
...
...
...
if playerX and playerturn then
button1.text = "X"
elseif not PlayerX and Playerturn then
button1.text = "O"
Else
button1.text = "err"

[xpertsword]

so basically i'm supposed to use 'And' instead of '&' ?
