HI, I just found out that when using the SUM function in App Connect data formatter, and let it sum the values of a mysql column with TYPE: DECIMAL 10,2 it does not do a good job. I get strange, wrong total values.
Does the formatter need an update or do I have to use a different approach.

I already tried to convert to number and then sum, but no succes:

{{sv_transacties.data.query1.sum(`ideal_bedrag.toNumber().formatNumber(2, ".", ",")`)}}

Any help much appreciated.

Hello Hans
Please explain what sums are you using, what is the result and provide a link to your page where we can check this.
