HI @Sowmya ,
I trust you are doing great.
You can do it using the client script on change one.
Once the value is changed into the list collector it will be passed to the backend where it will be shown as comma seperated sysIds for the reference.
var glideList = g_form.getValue('<glide list field>');
It will give output as sys_id1,sys_id2.
Then you can split it as given below :
var glideListArray = glideList.split(',');
if (glideListArray.length > 2) {
alert ('Invalid')
}
Was this answer helpful?
