Dear All,
How can I remove these errors?

1.WEAPApplication.Scenarios: Invalid Scenario: Current Accounts.

2.WEAPApplication.ResultValue: Invalid Branch: Variable name:\...

I tried to use Examples (using VB script) in WEAP API Classes But I can not understand what is wrong! also, when I run the code several times, the errors change! some disappear new ones appear! I am a beginner and need help very much!If you have a sample file about this, please share with me.
Thank you all for your attention.

Zahra and for anyone else wondering,

Best use practices of the API can be found in the WEAP Help- search for "Application API". You will need to ensure that your code is in the format listed for the scenario and resultvalue functions. The help lists the following examples:

PRINT WEAP.ResultValue("\Demand Sites\South City:Reliability") 'Reliability is for the entire study period, so doesn't have a year or time step parameter

SET S = WEAP.Scenario("Reference")
