FileMaker Pro Custom Functions

I've modified this function to use FM11's new highlight function. No need for color param.

/*
HiliteSingle function

Author
*COMMENT Visual Realisation

Format
HiliteSingle ( text ; searchString ; color )

Parameters
text - any text expression or text field;
searchString - any text expression or text field;

Data type returned
text

Description
Returns text with every occurrence of searchString in text highlighted.
The HiliteSingle() function is NOT case-sensitive. Occurences of searchString are matched regardless of case, and returned in their original case.


Updated to use FileMaker 11's highlight functionality

Hi,

First, thank you for the function. I'm having trouble saving it, though.
//TEST FOR MATCH
pos = Position ( text ;....)

I keep getting an error telling me that "text" is a specified parameter that cannot be found.

Any help on this would be great--thanks.

You need to define the three parameters ( text ; searchString ; color ) within the 'Edit Custom Function' window. See the help for more:

After having the function ready, how do I use it. Is is through a script or what?
Please give me an idea

Once you have defined the custom function, you use like any other function.
