Good Afternoon Guru's,

I am having an issue with an update query in ms access.

table structure:
                                         month1  month2   month3   month4  etc.......
grp1   money                        5.00       6.23        52.3         54.21
grp1   something
grp1   something1
grp1   average
grp2   money                        5.36        8.21        4.14          5.98
grp2   something
grp2   something1
grp2   average

Issue: We need to update each grp's 'average' line for each month based on the sum of all values in each respective grps 'money' line.
This is what is created so far, and I am running into syntax issues:

UPDATE ChartDBSource_Template
SET ChartDBSource_Template.Mar = ([ChartDBSource_Budget].[Mar] + [ChartDBSource_Budget].[Jan] + ([ChartDBSource_Budget].[Feb] + ([ChartDBSource_Budget].[Mar] + ([ChartDBSource_Budget].[Apr] + ([ChartDBSource_Budget].[May] + ([ChartDBSource_Budget].[Jun] + ([ChartDBSource_Budget].[Jul] + ([ChartDBSource_Budget].[Aug] + ([ChartDBSource_Budget].[Sep] + ([ChartDBSource_Budget].[Oct] + ([ChartDBSource_Budget].[Nov] + ([ChartDBSource_Budget].[Dec] / 12)
WHERE ChartDBSource_Template.CHART_BIN like 'BudAvg';

Your parentheses were off. The Nz is a IfNull function. Try this:

UPDATE ChartDBSource_Template
SET ChartDBSource_Template.Mar = ((Nz([ChartDBSource_Budget].[Mar],0) +
                                  Nz([ChartDBSource_Budget].[Jan],0) +
                                  Nz([ChartDBSource_Budget].[Feb],0) +
                                  Nz([ChartDBSource_Budget].[Mar],0) +
                                  Nz([ChartDBSource_Budget].[Apr],0) +
                                  Nz([ChartDBSource_Budget].[May],0) +
                                  Nz([ChartDBSource_Budget].[Jun],0) +
                                  Nz([ChartDBSource_Budget].[Jul],0) +
                                  Nz([ChartDBSource_Budget].[Aug],0) +
                                  Nz([ChartDBSource_Budget].[Sep],0) +
                                  Nz([ChartDBSource_Budget].[Oct],0) +
                                  Nz([ChartDBSource_Budget].[Nov],0) +
                                  Nz([ChartDBSource_Budget].[Dec],0) )/ 12)
WHERE ChartDBSource_Template.CHART_BIN like 'BudAvg';
