[SOLVED] create popup box with &ERRMSG displayed

In my focexec, there is an error checking routine (did the selection result in 0 records, etc). I'd like to send the error message to a popup box that has the &ERRMSG in it and an 'ok' button to return to the launch page. The &ERRMSG can be passed from the focexec and an HTMLFORM could be used to open the popup. I just don't have the code to create a popup box. If anyone can help me, I'd sure appreciate it! (I am javascript illiterate.)

I think that you will have to start reading up on javascript, as you will need it.

The most simple return is:
-SET &ERRMSG = 'Error Found' ;
-IF &FOCERRNUM NE 0 THEN GOTO ERROR ;
.
.
.
-ERROR
-HTMLFORM BEGIN
  <script language="JavaScript">
  <!--
    alert(&ERRMSG)
  //-->
-HTMLFORM END

-IF &FOCERRNUM NE 0 THEN :ERR;

-:ERR
-HTMLFORM BEGIN
<script>
var alertval = 'Error occured and it is ' + !IBI.AMP.FOCERRNUM;
alert(alertval);
</script>
-HTMLFORM END



Something of this sort basically...

Or If you dont want to go for custom JS alert, just think for a resizes and customized window.open() winodow or a Dynamic popup using
tag...


Thanks,

Ramkumar.

Thanks!
I took WAZ's idea:
WITHIN FEX:

-ERRCHECK
"be SURE to reset &ERRMSG at the top of error checking"
-SET &ERRMSG = '';
-SET &ERRMSG = IF &LINES EQ 0 THEN
'No Data Found For Your Selecton' ;
-SET &ERRMSG = IF ..... THEN 'Error Text' ;
-IF &ERRMSG NE '' THEN GOTO ERROR ;
.
.
.
-ERROR
-HTMLFORM BEGIN
<script language="JavaScript">
alert(&ERRMSG.EVAL)

-HTMLFORM END
-EXIT

The first error will show up in the popup box. If there are multiple errors, the next one will show up on the next attempt to execute the fex, etc.

You could also build a list of messages.

By adding each error message to the &ERRMSG variable, and separate each one with '\n', a new line, you can have a better message.

Sounds good, Waz: Can you show me an example?

Here is an example of building the list.

-SET &ERRMSG = ' ' ;
-SET &ERRMSG = IF {condition} THEN &ERRMSG || 'My First Error\n' ELSE &ERRMSG ;
.
.
-SET &ERRMSG = IF {condition} THEN &ERRMSG || 'My Second Error\n' ELSE &ERRMSG ;
.
.
-SET &ERRMSG = IF {condition} THEN &ERRMSG || 'My Other Error\n' ELSE &ERRMSG ;
.
.
-IF &ERRMSG NE ' ' THEN GOTO ERROR ;
.
.
.
-ERROR
-HTMLFORM BEGIN
  <script language="JavaScript">
  <!--
    alert(&ERRMSG)
  //-->
-HTMLFORM END


The \n in the text creates a new line in the javascript alert.
