assign variable from query to same variable in planning sequence

Hi everyone,

I am trying to bild a very small planning application in design studio.

it should consist of on table with a query and 3 buttons starting planning sequences.

The sequences use variables, which are selected by line selection in the table and by the variables used in the filter of the query.

For one of the filter variables it works fine.

I used

mysequ.setVariableValue("var_year", myquery.getVariableValueExt("var_year"));

in Events on Startup

my year object is referencing to 0CALYEAR.

when I do exactly the same for my secon variable for month, this is not working.

When I run the sequence, I get the error message, that I should fill the variable value.

My month object is referencing to 0CALMONTH2

I suspect, that this getVariableValueExt - giving me some external value is not right. But there is nothing else abailable.

I also tried to use the getfilterext but it does not work.

I also used it directly in the button where I start the sequence, but again it does not work

So which command shall I use to hand over variable values from the query filter to the variable in a planning sequence?

Thanks

Cornelia
