New to fields, how do I re-use a DateCalc example in a mail merge?

[Andy.T]

Hi there,



Sorry, I'm very new to all this, please bear with me.

I've inherited a mail merge document and I need to add a new field that displays the 1st of next month based on a value in my source data (a column called Date_First_Payment).

e.g. If Date_First_Payment = "10/07/2024 00:00" then I'd like to show "1st August 2024".

I've had a look at DateCalc V2 and it looks like there's a brilliant function there that I can tweak slightly to give me what I want, "Calculate the day & date of the nth day of next month".

However, I'm a bit lost as to how I'd actually get that function pointed to the datasource value of Date_First_Payment, rather than today's date.

I've tried removing the "Date" and then, in its place. inserting my Date_First_Payment mailmerge field, but I get...

1-!Syntax Error, ,-2024

I'm not sure if it's just the way I'm adding the field in that's wrong, or if the presence of the time "00:00" in my data value, is what is scuppering it?

Any pointers would be greatly appreciated.

Thanks a lot,

Andy
