$ sign missing

I’m including a file, using these tags:

[insert_php]

include(“/local/home/directory/index.html”);

[/insert_php]

but if there is a dollar sign in that file, it will strip out the $ and also the numbers after that until it reaches a comma. So $70,000 becomes ,000

Is there any fix for this?
