Hi @davepokpong,
Could you be more specific about the criteria here?
For this exact solution, CFernandes' solution is perfect, but as he said, it'll only work if the first character is a "1". Just by looking at your question, I can see a few different logical methods that could be applied (which would require different methods).
- Removing all text from the string, leaving just numbers
- Removing the first 3 characters of the string
- Remove everything before the first "1" (Cfernandes has answered this one)
If you can clarify the requirements, you'll get a much more suitable answer 🙂
