Where am I wrong? Function Left_Trigger(ByVal Item) Dim objTag, Value1, objRectangle, objRectangleItem Set objTag = HMIRuntime.Tags("move") Set objRectangle = ScreenItems("Rectangle1") Do While objTag.Read() = 1 Do objRectangle.Left = objRectangle.Left + 10 Loop Until objRectangleItem.Left() = 600 Loop End Function

You can manipulate the Postion X & Position Y attributes in the object itself or you can change position attributes "outside" the object (in a button for example). In VBS you can use the Top and Left attributes. Find attached a simple example in VBS. In this exampleeverytime you click the button, the circle moves by 20 X and 20 Y.

Each trigger cycle move to the right until the limit or move it once to exact position? And imho you can use directly "Item" (suppose the script ison the rectangle) don't have to define the object. For the first situation the script could be something like this: Dim objTag Set objTag = HMIRuntime.Tags("move") If (objTag.Read = 1) And (Item.Left < 200) Then Item.Left = Item.Left + 10 End If Regards Sydney

This place is not important. the rectangle can be placed at X 300 400 etc... only when the tag move changes to 1 ; the rectangle must move at the X plane 10 by 10 until its pos X becomes 600. I used "objRectangleItem.Left() = 600" to read the position of the rectangle. And this was wrong. I see. Sydney: your code worked. thanks. Set objTag = HMIRuntime.Tags("move") If (objTag.Read = 1) And (Item.Left < 600) Then Item.Left = Item.Left + 10 End If for the stars i thank to cumulus. I am a new member and this encouraged me to write in this forum.

On a serious note, one of the moderators should cut my reply in the above thread and paste the in to this thread (and close the above thread) Regards
