I am getting this error when entering my formula of: =15.1 + (21.8 * (j2)) - (0.327 * (h2)) (0.263 * (j2) * (c2)) + (0.00504 * (h2) * (c2)) + (5.98 * (b2)) To get assistance in entering a function, click OK,then click Function on the Insert menu. If you are not trying to enter a formula, avoid using an equal sign (=) or minus sign (-), or precede it with a single quotation mark (').
