Hey guys......... 
I am reaching out to seek your assistance regarding an error I’ve encountered while trying to run a stock screening strategy on the Portfolio123 platform.
I have been working on a custom screen that utilizes several filters, including market capitalization, earnings growth, and technical indicators. However, when I attempt to execute the screen, I receive an error message stating, "Invalid parameter in screen configuration." I’ve double-checked the parameters I’ve set, and everything appears to be in order according to the guidelines provided in the documentation.
To provide more context, here are the specific parameters I’ve included in my screen:
- Market Capitalization: Filter set to “Large Cap”
- Earnings Growth: Targeting companies with a minimum growth rate of 10%
- Technical Indicator: Using a 50-day moving average crossover
I’ve also tried simplifying the screen by removing some filters to see if the issue persists, but the error continues to appear. This has left me puzzled, and I’m unsure whether it’s an issue with my setup or if there’s something else going on with the platform.
I also check this: https://community.portfolio123.com/t/error-message-when-accessing-subscribed-r2g-portfolilooker If anyone has encountered a similar issue or has any suggestions on how to troubleshoot this error, I would greatly appreciate your insights.

Thank you in advance for your help!
