User Entry with Number Edit Box not working

[#1]

Hello - I've got this confusing issue where I have a nested number edit box, and for some reason its not sending the entered number into the variable I've got it set to. I tried selecting and running only that line, and low-and-behold it sends the info to the variable, but for some reason in context, it refuses to do it. I actually got it to work a while ago, but then I went to bed, got up, didn't change a thing before it (I changed the script it calls as well as added a couple of "write to column" lines farther down), and this happened, so I'm a bit confused. Here's the code up to the <<get line, but if you want the whole code, its attached in a file:

Clear Symbols();

w = New Window( "Choose Row Number for XRD Run input", // opens a window with a title and this content...
	Border Box( top( 20 ), bottom( 20 ), Left( 20 ), Right( 20 ), // window dressing 
		V List Box( // V and H lists nest to organize the display boxes
			H Center Box( Text Box( "Choose Row Number for XRD Run input" ) ), // a second title, centered
			Spacer Box( size( 1, 30 ) ), // a little vertical space
			H Center Box( rowtemp = Number Edit Box( 116 ) ), // data entry
			Spacer Box( size( 1, 10 ) ), // a little vertical space
			H Center Box( // center the button
				Button Box( "Import Smaple Data", // this script runs when the button is pressed...
					rownumber = rowtemp << Get;

Also, side question, but when I get to the w << close window statement, it says

Send Expects Scriptable Object in access or evaluation of 'Send' , w << /*###*/closeWindow/*###*/

, which confuses me, because again, this worked earlier, and it also follows the syntax correctly. If anyone knows why that's happening, that would be helpful too.

Thanks in advance.

I would set the value within the Number Edit Box using a <<set function

Clear Symbols();

w = New Window( "Choose Row Number for XRD Run input", // opens a window with a title and this content...
	Border Box( top( 20 ), bottom( 20 ), Left( 20 ), Right( 20 ), // window dressing 
		V List Box( // V and H lists nest to organize the display boxes
			H Center Box( Text Box( "Choose Row Number for XRD Run input" ) ), // a second title, centered
			Spacer Box( size( 1, 30 ) ), // a little vertical space
			H Center Box(
				rowtemp = Number Edit Box(
					116,
					10,
					<<SetFunction( Function( {thisBox}, rownumber = thisbox << get ) )
				)
			), // data entry
			Spacer Box( size( 1, 10 ) ), // a little vertical space
			H Center Box( // center the button
				Button Box( "Import Smaple Data", // this script runs when the button is pressed...
					//rownumber = rowtemp << Get
				)
			)
		)
	)
);

@txnelson Thanks for the suggestion! I've added it in.

Unfortunately it didn't do much. My firewall is blocking the debugger for some reason, so I had to resort to wait/show commands, and realized I was less familliar with the Clear Symbols() function than I thought. My called script started with a clear variables command, so that accounted for the killing of the rownumber variable, as well as the w << Close Window command not working, as "w" was being removed as well.

Methinks I don't understand namespaces enough.

Thanks for the help!

In very short for namespaces:

• Start all your scripts (always) with Names Default To Here(1);
  • Local Namespaces (jmp.com)
• Don't leave Clear Symbols(), Clear Globals(), Delete Symbols() or Delete Globals() to any (production) scripts as they can potentially mess up whole JMP session (use them only for debugging).
  • Show Symbols, Clear Symbols, and Delete Symbols (jmp.com)

And both of these are good reads: Global and Local Variables (jmp.com) and Rules for Name Resolution (jmp.com) (remember to check also subtopics)
