Forums Scripts & Popups question on $null checking..

hello again,

i seem to be having a brian fart, so i'm asking this really dumb question. reffering to dialog editboxes, if i want to to check if a %var has data or exists i would like it to return the %vaiable result if not then i would like it to return N/A in the editbox. i know this is lame but i can't figure it out..
i've tried :

but that doesn't work ...... was i even close??

if anyone would be willing to help with this dumb thing it'll be appreciated greatly..

if ([color:red]!%variable) { commands }[/color]

Eamonn.

That if statement will fail if %variable not just contains no value, but also if it is 0 or $false. Just in case I'd check if (%variable = $null), if (* !iswm %variable) or even if (!$len(%variable))

thanks sigh,

" if (* !iswm %variable) " is a winner!!!! it did the trick

you are da-man sigh!
