How to Highlight a Cell Based on the Value of Another Cell

[djbateman]

I am trying to highlight a cell in an output table based on certain criteria.  From the table below, I just want to output LINETEXT, RESULT, and PREF_RESULT.  If RESULT is not the same as PREV_RESULT, then I want to highlight RESULT.  In the compute block I have tried if RESULT^=PREF_RESULT or if DIFF_FLAG=1.  If I compare RESULT and PREV_RESULT in the compute block, it highlights the entire column.  If I use DIFF_FLAG=1, then I get a note that DIFF_FLAG is uninitialized and no highlighting happens.  Can someone tell me what I am doing wrong?

As a side note, I'm also trying to bold any row that has LINENO=0, but I'm getting the same uninitialized message as with DIFF_FLAG, so I've tried a different method as shown in the code below.  I would like to go back to the LINENO=0 logic if I can figure out the DIFF_FLAG.

Proc report builds reports left to right. So a compute block for a variable typically cannot see the result of a column to its right in the display.

Use a compute block for prev_result and use that to set the highlight using call define(results,<properties>)

Oh my goodness!  I figured it out!

I was simply leaving out "display" in the define statement for DIFF_FLAG.  Don't you love when you spend half a day trying to find the one word that solves all your problems?

Here is the working code for those that are looking at this post to solve their own problem:

proc report data=execsum;
	column lineno diff_flag linetext result prev_result;
	define lineno / display noprint;
	define diff_flag / display noprint;
	define linetext / display left 'Category';
	define result / display left "Current Response (&sysdate9.)";
	define prev_result / display left "Previous Response (&prev_date.)";
	compute linetext;
		if lineno=0 then call define(_row_,"style","style={font_weight=bold}");
	endcomp;
	compute result;
		if diff_flag=1 then call define(_col_,"style","style={background=yellow}");
	endcomp;
run;
