sumif where word found within string

[Soren]

Is it possible to construct a simple formula, along the lines of "sumif".
The data range has descriptions in column A, and sales figures by month in columns b through Z.
What I need is a summary total by month of all the lines, where a known sting is found within the description in column A. There are multiple known strings that this needs to cater for.

Can you post a sample dataset of what you are looking to do? Will make it easier for people to help

Found the solution as :

=SUMIF([description_range],"*"&[variable string to find]&"*",[sum_range])

thanks for assistance
