If you assign flexscript to a table cell that is does not need any external paramters then you can use the standard syntax "Table(tableName)[row][col]".

To pass in parameters, access the node of the cell and use "evaluate()" on it. ("Table(tableName).cell(row, col).evaluate(params)")

The thing is I want to create a varible as a trigger "on entry" of a sink to count items with the following code:

gettablecell(label(current,"ItemCounts"),item.Type,1)

For this reason, I need to specify the varible "As.Table"

The questions would be:

· Where in the triggers could I create the variable?

· How could I speccify to the trigger that is a table?

· Where could I add the code mentioned previosly in the trigger?

You don't need to create a table variable for that command. Either the label node has the correct structure for a table and the command works or it doesn't.

The non-deprecated expression would be "current.labels["ItemCounts"].as(Table).cell(item.Type, 1)". In this case the as.(Table) is needed for the compiler to recognize cell() as a valid method.

Hello @Felix Möhlmann

Thank you vey much for your detailed answer. It has been very useful.

I have some questions related to this:

Could it be posible to repeat the demad table from the start once it is finished and continue with the time?
What information gives me in a practical way the itemcounts varible table?
Could it be possible to define an hour in each day to start pulling the items to the sink?

Thanks a lot!

Best regards,
