Single step works fine but command button has errors

I have a long but simple VBA program that hides rows in a spreadsheet depending upon options. Everything works fine when I single step through the program using F8. However, that is not the case when I use a command button to execute. For example, there are eight rows each for Slots C, D and E. For the specific variables, the coding should hide none of C, 4 of D and all of E in workbooks '700G Relay Setting Calcs' and 'Logic Variables'. It does so successfully with single step using F8. When pressing the command button within the spreadsheet, it hides 5 instead of 4 D in workbook '700G Relay Setting Calcs', and none of D and only 3 of E in workbook 'Logic Variables'.

I don't understand how it would work using F8 but not work when runing the macro automatically. Any ideas on where to start looking for the issue? A sample portion of code follows:

Hi

I think you need to post all of the code rather than a snippet, especially if there is any external data involved.
