Passing multi selected values from a combo box to a focexec

Hi,
I have a requirement. I have a combo box that allows multiple selects on a HTML Launch Page.
I need to pass the multiple selected values to a FOCEXEC.
But I noticed that only the first value that is selected from the combo box is passed on to the focexec.
I also tried capturing the values that are selected from the combo box using Javascript on the HTML Page.
The alert message displays only the first value that is selected instead of the multiple values.
Can anyone, please suggest me a way to solve this issue?
Thanks in advance.
Regards,

Mariea, here's how that works.
when you pass just a single choice for, say, &MYVAR, its easy, you can just say in your fex
IF SOMEVAR EQ &MYVAR
However, when you set up a select list as 'multiple', different stuff happens.
You now get
&MYVAR0 (thats a zero) which is the number of values that have been selected
&MYVAR1
&MYVAR2 , etc...up to n, where n = &MYVAR0.
What i do is
DEFAULT &MYVAR0 = 0 ;
that effectively sets my counter off, and allows me to test the value later.
So you can loop from 1 to &MYVAR0
-SET &KOUNTER = 0;
IF SOMEVAR EQ &MYVAR1
-REPEAT endloop &MYVAR0 TIMES
-SET &KOUNTER = &KOUNTER + 1 ;
OR &MYVAR.&KOUNTER
-endloop
Here's the trick; If the user selects ONLY 1 thing, then &MYVAR0 doesn't get passed . that's why defaulting it is a good idea.
and &MYVAR1 doesn't get created, only &MYVAR
When the user selects at least 2, then &MYVAR0 does get created, and both &MYVAR and &MYVAR1 get created, they're the same!. Way cool
so your loop will work from &MYVAR.&KOUNTER where &KOUNTER is 1. (gotta put that dot in between the varname and the kounter value)
See? cool.

Hi Susanah,
I was away at a client place and hence the delay in getting back to you. I used your technique and have solved the issue. Thanks for your assistance.

Mariea
