Strange Error Executing Table Cell

I am trying to execute a probability distribution that is in a global table cell. I would like to assign the result to a label, and also use the value to define a delay.

It is strange that is works perfectly on one computer. On the other computer I am getting this error:

exception: FlexScript exception: Property "dataType" accessed on invalid node. at MODEL:/Tools/GlobalTables/GlobalTable1>variables/data/Row 1/Col 1

Here is the test model:

Distribution_From_Table_RevA.fsm

Thanks!

Software Version:

FlexSim 21.2.4

global table

The error is complaing about calling getstream() in your code. To properly use streams in a global table, you need to make two changes:

Change your code in the global table to say
```
 uniform(10, 20 param(1))
```
To pass in the stream, you need to evaluate the cell. In the Assign Labels, use
```
Table("GlobalTable1").cell(1, 1).evaluate(getstream(activity))
```

I will also say that this feels like a model parameter. You can add a parameter (in a separate Parameter Table, if you want), and set its type to Expression. Then you can add the exact same code in step 1 above. The step 2 code would change to:

Model.parameters["MyParameter"].evaluate(getstream(activity))

Thanks for you response. The model works after making the changes.

I think there is a comma missing in your code for the global table.

uniform(10, 20, param(1))

I agree, this could be a model parameter. I will look into it. In the parameters table, I am not sure what to set as reference and On Set. I using the eyedropper to reference one of the delay activities but it does not accept it.
