Description:
CALC will allow you to delete a STYLE if it is not used in any formula in any sheet even if it IS used in a conditional format.  The STYLE delete function needs to be corrected so that it also cross-references a STYLE in conditional formats before it will allow you to delete it.  The Find/Change function also needs to be enhanced to search and replace a STYLE in conditional formats as well as formulas.

Steps to Reproduce:
1.Create a STYLE.
2.Create a conditional format that uses the STYLE.
3.DO NOT use the STYLE in any cell formula.
4.Delete the STYLE.

Actual Results:
The STYLE is deleted and the STYLE field in the conditional format is blank

Expected Results:
You should not be able to delete the STYLE.


Reproducible: Always
