Hello,
Yes it is possible though the use of VBA. I can not think how to acomplish this with Conditional Format or formula.
Right click the sheet tab >>
Veiw Code>>
paste in:
******************************************
<font face=Courier New><SPAN style="color:#00007F">Private</SPAN> <SPAN style="color:#00007F">Sub</SPAN> Worksheet_Change(<SPAN style="color:#00007F">ByVal</SPAN> Target <SPAN style="color:#00007F">As</SPAN> Range)<br><br> <SPAN style="color:#00007F">If</SPAN> Range("A1").Value >= 10 <SPAN style="color:#00007F">Then</SPAN><br> ActiveSheet.Shapes("TextBox 1").Fill.ForeColor.RGB = RGB(255, 0, 0)<br> <SPAN style="color:#00007F">Else</SPAN><br> ActiveSheet.Shapes("TextBox 1").Fill.ForeColor.RGB = RGB(255, 255, 255)<br> <SPAN style="color:#00007F">End</SPAN> <SPAN style="color:#00007F">If</SPAN><br> <br><SPAN style="color:#00007F">End</SPAN> <SPAN style="color:#00007F">Sub</SPAN></FONT>
******************************************
Modify "Text Box 1" to your text box name. (this uses a textbox from the insert menu in Excel 2007.)
Modify "A1" to your cell reference
Modify >= 10 to meet your criteria
Modify RGB(255,0,0) to your color choice
(The code turns red when value in cell A1 is greater than or equal to 10
if not the textbox color is white.)
Close the VBEditor>>
change any cell on your sheet.
