Hi All,

I'm trying pass the power automated output variable %AttributeValue% with a text of "IN998877 - A-BB-CCC-DDEERFFFFRE FR" to a run VB Script to extract the output of "IN998877", but it seems neither var %AttributeValue% is not picking the value or not knowing how to be assigned with. so please help to resolve it.

Dim inputText, startPos, endPos, extractedText

inputText = %AttributeValue%

'inputText = "IN998877 - A-BB-CCC-DDEERFFFFRE FR"

startPos = InStr(inputText, "IN")

endPos = InStr(inputText, " -") - 1

If startPos > 0 And endPos > 0 Then

    extractedText = Mid(inputText, startPos, endPos - startPos + 1)

    WScript.Echo extractedText

Else

    WScript.Echo "Text not found"

End If

Add double quotes around the variable:

Dim inputText, startPos, endPos, extractedText

inputText = "%AttributeValue%"

'inputText = "IN998877 - A-BB-CCC-DDEERFFFFRE FR"

startPos = InStr(inputText, "IN")

endPos = InStr(inputText, " -") - 1

If startPos > 0 And endPos > 0 Then

    extractedText = Mid(inputText, startPos, endPos - startPos + 1)

    WScript.Echo extractedText

Else

    WScript.Echo "Text not found"

End If

Then output was: IN998877

Always good practice to add ScriptError output variable on Script actions:

ScriptError value:

That says the problem is at line 3

Then your variables seems to work so its more about the value inside the variable or the extraction logic. Can you show a screenshot of the AttributeValue variable on PAD? Make sure in your VBScript only the %AttributeValue% has double quotes around it and not VBScript own inputText variables. So only add doublequotes around the %AttributeValue% in your original code you posted.

You can test that the variable assignment actually works with adding to the else echo: WScript.Echo "Text not found from " + InputText

Then you would get the variable value in the "Text not found" result:

(I intentionally changed the variable values starting I -> i to get the not found condition)

How it works with your code when I have the
inputText = "%AttributeValue%"

If the ScriptError is empty then the VBScript didn't go in to error so the condition just wasn't met.
