What is wrong with this scenario?

[GEOSoft]

; Script Function:
;   Convert KB article number to URL
;
$a=clipget ()
StringStripWS ($a,7)
If StringLeft ($a,1)="Q" Then $a=StringTrimLeft ($a,1)
If StringIsDigit ($a)="0" OR StringLen ($a) <"5" OR StringLen ($a) >"6" Then 
    MsgBox (4096,'Error!!','The clipboard does not appear to contain a valid MS Knowledge Base article number'&@LF&'Please check your selection again and retry.')
    Exit
EndIf
ClipPut ('http://support.microsoft.com/?kbid='&$a)
MsgBox (4096,'', 'DONE!!',1)
Exit

I will use Q178238 as the example. If the line contains

Q178238

and I double click the number to select it then copy it to the clipboard,

the Q should be stripped (it is) and then it is checked to make sure it is a numeric value of either 5 or 6 digits (so far so good). If I add a space to the end of the line and repeat the process, the StringStripWS ($a,7) should be removing the trailing space. This is where it fails. I get the MsgBox (Error) showing instead.

StringStripWS ($a,7)

should be:

$a = StringStripWS ($a,7)

:iamstupid: Duh!!!

That probably applied to the other workarounds I tried too. Thanks Jon.

By the way can you use multiple conditions in Do....Until or While loops?

eg;

Do

<whatever>

Until <condition 1> OR <condition 2>

While <condition1> OR <condition2>

<whatever routine>

i dont see why not, try it. <condition 1> OR <condition 2> is the same as <condition3> to the computer, and so it would be interpreted as Until <condition 3>. i think. did that make sense?

Yep. JP has done one that's about 5 lines long...for testing purposes
