There is a lower () function available. It can be used in conjunction with the Set Field command to convert the string to lower case.
It's been awhile since I've worked in FileMaker but... won't this force ALL my text to lower case?? I only want the actual html coding to be lower case...
If the links are inside the field of "html" - yes - however to do just the links <href etc... would require them to be in separate field(s) OR you could use additional scripting to selectively lower () case the strings that are found to be links within that larger html page - not as easy but could be done - depends on how much work one is willing to devote for the benefit. The methods are somewhat limiting in this version.
Is there any way I can have Filemaker export in lower case html??
If you mean export as HTML table, then no - there's no control over the HTML coding. However, you can export as XML and use a XSLT stylesheet to convert the result to HTML - see the examples in the XML Examples folder installed with the application.
