Passing V[_tabrow] to an InputScript: I use the V[_tabrow] variable in order to pass the current table row number to an InputScript:

Pushbutton(toolbar) "Test" process= "test_tabrow.txt"size=(1,3) using ITEM = "&cell[Table,AFVGD-LTXA1,&[_tabrow]]"

InputScript:
Parameter ITEM

Message "&U[ITEM]"

But this does not work as I expected, since I need an additional "ENTER" in order to obtain the right table row. What could be the reason?

Use the expression

"&cell[Table,AFVGD-LTXA1,&[_tabrow]]"

in the InputScript. When you use it in the GuiXT script, &V[_tabrow] has already been evaluated when the screen is displayed, but you need to have it evaluated it when the user presses the button.
