Hi

I am trying to dynamically change an email recipients list based on a selection that the user will make. I pull the email addresses from the database and then I group concatenate them into a string with a separator between them. When I assign this string to the script it is adding quotes before and after the string which I believe is leading to errors when I try to send the email. I have tried various combinations of double and single quotes but no success. if I type it the addresses manually with double quotes around them as in the manual example it works ok.

This is the type of string I am assigning in the script to the variable [color=#FF0000]Contacts[/color]  
“bob@yahoo.ie”,“bob@gmail.com”  
I have tried removing the quotes and adding single quotes,three quotes but none work

[color=#FF0000]Contacts = event.source.Recipients  
#NEW DATASET READY TO BE SENT IN EMAIL  
newDS = system.dataset.toDataSet(TableHeader, Data)  
#Convert DataSet to HTML For Sending In EMAIL  
EmailHTML = system.dataset.dataSetToHTML(1, newDS, “MAINTENANCE REPORT”)  
Emailbody = “

# MAINTENANCE REPORT
”+ EmailHTML  
EmailRecipients = [Contacts][/color]

This is the error I get when I try send the email.

Thanks

Aidan

It looks like you have a single string with all the contacts in that string. What you need is a python list that has your email address entries. Try replacing this:

`
EmailRecipients = [Contacts]`

With this:

`Contacts = Contacts[1:-1].split(',')
EmailRecipients = Contacts`

The split will convert your single string to a bonafide list. 😃
