How to use regExp in Word VBA code to find a keyword in a word document?

Question

I'm triying to use this regExp pattern ^SFT(-[A-Z]+){2,3}(-\d+)$ to find a key word in a Word document with VBA Excel but it doesn't work and I get a 5625 error due to special caracter.

Anybody knows how to solve out this?

Examples of data I'm triying to find:

SFT-LTE-SEC-8, SFT-LTE-ROLES-PMR-1, SFT-LTE-MCPTT-2

There are numerous errors in your code so I have added comments to show where they are and how to fix them.

You will still need to fix the wildcards as there isn't enough data in your question to identify your exact requirements. You can find details on using wildcards at the Word MVP site: https://wordmvp.com/FAQs/General/UsingWildcards.htm
