GetRGB function

Author
*COMMENT Visual Realisation

Format
GetRGB ( text )

Parameters
text - any text expression or text field

Data type returned
text

Description
Returns set/s of RGB values representing the colors of text. If text contains multiple colors, multiple sets of RGB values are returned.

Note:
The GetRGB function ignores field text color, as defined in layout mode. The values returned represent colors that were expressly defined to override the default color setting (e.g. by selecting the text and choosing a text color, or by using the TextColor() function).

I'd like to use this function but it contains a syntax error that I can't seem to overcome when I put it into my Custom Functions.

After adding the function parameters "text" and "GetRGB" -- FileMaker says that an operator is required in this line:

GetRGB ( nextText )


I'm stumped not knowing which operator is required.

This works great, except I cannot use it for boolean, for some reason. I am trying to use it in a script, as in If GetRGB(myText) = "255 ; 0 ; 0 ", but it is always false, even when I copy the result from the Data Viewer. Any ideas? It says it is 12 characters long and appear to be spaces, but I cannot get it to come back true. GetRGB returns the result, then I copy the result and past it into the IF, but it doesn't think it's own answer is true.

Thanks for any help.
